Title: Solventless polymeric composition comprising non arylamine, polyacrylate and epoxide

Description:
BACKGROUND OF THE INVENTION 
     I. Field of the Invention 
     The present invention relates to solventless polymeric compositions and, more particularly, to generally liquid, low viscosity polymeric compositions which polymerize by means of an addition reaction mechanism. 
     II. The Prior Art 
     Many different types of liquid polymeric materials are known in the prior art and are used in numerous applications. For example, liquid polymeric compositions can be used for paints, coatings and films, or can be poured into molds or substrates to make castings. However, the various physical properties of these polymeric compositions present certain problems in many applications. For example, compositions having generally high viscosities or rapid reaction rates are difficult to apply as films or coatings without the use of solvents to dilute or dissolve the components. This normally creates pollution problems, however, when the solvent evaporates. Additionally, as the solvents evaporate they can leave voids or blisters in the polymeric material. 
     Accordingly, there exists a need in the art for solventless liquid polymeric compositions which can be used in paints and coatings, and which can be poured into molds to make castings. As used herein, the term &#34;solventless&#34; means the absence of any solvent in the components utilized to make the polymeric composition which does not take part in the reaction. Thus, upon mixing the various components, there is no solvent to be evaporated or entrapped into the resulting thermosetting polymeric materials. In other words, the whole system is 100% active and there is no waste through solvent evaporation. Under such solventless conditions, compact films or parts are formed which are void free, since there are no solvent losses through evaporation or solvent entrapments to cause porosity and blistering. 
     Furthermore, the absence of solvents eliminates environmental pollution caused by solvent loss. In this respect, solventless systems are even better than waterborne polymeric materials because the latter contain small quantities of ammonia, amines and solvents used as water emulsifiers, solubilizers and stabilizers. Conventional solution polymeric materials used for coatings and paints contain substantial amounts of solvents or water which are lost by evaporation to the environment. Solventless systems have no evaporation problems and provide economy with their efficiency. 
     Based on the same weight and thickness of a coating, solventless polymeric systems provide considerably more surface coverage than solution systems because the solventless systems are 100% active. In addition, solventless systems are more compact with respect to production capacity, storage room, transporation room, and are safer, with less attendant health and fire hazards. 
     The best solventless compositions are thermoset through an addition polymerization mechanism. This simply means that component A reacts with component B by adding to it without the formation of any volatile by-products which could cause voids, blisters or entrapments in the film or part. These polymers can include ladder-like type polymers wherein the components are cross-linked spacially in the form of a ladder. For example, two linear parallel polymeric chains are intersected at their repeated reaction sites by components which form the steps of the spacial ladder. 
     The few ladder polymers which are known generally in the art have exceptionally good chemical resistance. However, these compositions are generally solids and are insoluble in organic solvents. Additionally, these ladder-type polymers generally have to be heated above 180° C. to effect curing. Thus, it is extremely difficult to use a ladder-type composition as a paint or coating. 
     It would also be advantageous to have a solventless polymeric composition in which the various components are liquids with relatively low viscosities at ambient temperatures. Such systems would be advantageous because they could be conveniently applied as coatings by spraying, dipping, brushing, rolling, or the like. 
     Additionally, liquid, solventless compositions can be more easily mixed together with pigments, pigment extenders, dyes, fillers, carbon, glass or organic fibers without the necessity of dilution with solvents. Low viscosities greatly facilitate any grinding process and the absence of solvents reduces the fire hazard caused by the heat of friction in the presence of volatile and flammable organic solvents. Thus, the systems can readily be utilized to make paints and coatings. 
     Conventionally known polymeric materials used in coatings and paints have typically been of one or two component systems. The one component systems are generally always water borne and comprise solution or emulsion type materials in organic solvents such as oil alkyds, epoxy esters, urethane oils, and latexes. Two component systems generally include: 
     (a) solid or liquid epoxides and polyamines, or amine terminated polyamides; 
     (b) isocyanate terminated polyurethanes and di or polyols, hydroxyl terminated polyurethanes and/or p,p&#39;methylene,o,o&#39;, chloro dianiline; 
     (c) unsaturated polyesters; and 
     (d) photoprepolymers. 
     Presently available one component liquid polymeric systems have several distinct disadvantages. For example, the compositions can only be applied in thin coats so that the solvent can evaporate. Additionally, as the solvent evaporates, it can leave voids or blisters. 
     The two component systems also have certain disadvantages. For example, these systems which include epoxides have required a solvent to dissolve the epoxides such that they can be easily applied. Even the normally liquid diepoxides such as those based on Bisphenol A and epichlorohydrin (exemplified by EPON-826 and EPON-828 sold by Shell Chemical Company and others), have viscosities greater than about 4,000 centipoise (CPS) at ambient temperatures. Other liquid di or polyfunctional diepoxides of glycidyl ethers with Bisphenol A, as well as the liquid diepoxides of Novolac type, have viscosities much greater than 4,000 centipoise. When these liquid epoxides are cured with polyamines such as triethylene tetramine (TETA), or liquid amine-terminated polyamides such as the Versamides produced by General Mills Company, additional solvents must be used to reduce the viscosity. This is because when the epoxide and amines are mixed together, there is no viscosity decrease, but rather a rapid increase due to the high reactivity and functionality of TETA with the epoxides. 
     Both isocyanate and hydroxyl-terminated polyurethanes such as Adiprene L-100, Adiprene L-150 (produced by E. I. duPont de Nemours &amp; Company of Wilmington, Del.), Multrathene-2680, Desmophens and Desmodurs (produced by Mobay Co.) have viscosities in excess of 18,000 centipoise or are solids at ambient temperature. Therefore, these compounds cannot be used as components of a liquid, solventless system. 
     Unsaturated polyesters such as the condensation product of maleic anhydride, phthalic anhydride or isophthalic acid with 15% to 25% molar excess of 1,2 propylene glycol diluted with 30% to 50% by weight of styrene monomer have been used as good, solventless systems when combined with 1% by weight of a ketone hydroperoxide catalyst and 0.3% by weight cobalt naphthoate as an accelerator. However, the volatility of the odorous styrene monomer, the highly critical 100/1/0.03 weight ratio and the very rigid and inflexible thin films which are produced make the styrene diluted unsaturated polyester system unsuitable for coatings or paints. However, these unsaturated polyesters are broadly used in combination with fiberglass to produce reinforced plastics. 
     Perhaps most similar to solventless systems are photoprepolymers composed of di or polyfunctional acrylates diluted with monofunctional acrylates containing polymerization inhibitors, photoinitiators (catalysts), and photoaccelerators (tertiary amines). However, these formulated prepolymers have limited storage life and have to be protected from contact with ultraviolet light. Additionally, the curing of these compositions requires strong sources of ultraviolet light or electron beam. These sources are generally accompanied by strong infrared light which causes evaporation of the unpleasantly smelling monoacrylic esters. Additionally, only films of a few mils in thickness can be fully cured. As soon as the surface of the photo prepolymer is exposed to ultraviolet light or electron beam it hardens, thus inhibiting further penetration of the ultraviolet light. This self inhibition problem of photoprepolymers is even more acute if the polymer contains pigments or fillers. Thus, photoprepolymers are generally limited to applications requiring very thin, and preferably clear, films. 
     In view of the foregoing, it is obvious that it would be a significant advancement in the art to provide a solventless polymeric composition which could be used for coatings and paints and also which could be poured into substrates or molds to form castings. It would be still a further advancement if such a solventless system had a liquid consistency of a relatively low viscosity at ambient temperatures. 
     SUMMARY OF THE INVENTION 
     The present invention provides solventless polymeric compositions formed from the reaction product of a first component comprising mono, di or poly amines, amine-terminated structures or an adduct of mono, di or polyamines with mono, di or polyfunctional acrylates or epoxides; and the second component comprising mono, di or poly acrylates, mixtures of mono, di or poly acrylates, or a mixture of mono, di or poly acrylates and mono, di or polyfunctional epoxides and/or glycidyl esters of acrylic acid or methacrylic acid. 
     In a first embodiment, the first and second components are formulated such that they are both liquids having a relatively low viscosity at ambient temperatures. Thus, the components can be mixed together and can be applied as a coating or paint by spraying, dipping, brushing, or rolling, or they can be poured into substrates or molds to make castings. 
     In a second embodiment, the first component comprises a mono, di or polyamine, hydrazine, or an amino-hydrazine terminated derivative and mixtures thereof either alone or in combination with mono, di or poly acrylates. The second component comprises a mono, di or poly acrylate and the first and second components are mixed together in proportions such that the number of acrylate linkages are in excess of the aminic hydrogens so as to form a photoprepolymer. This photoprepolymer can be utilized to form thin films or sheets and can be further polymerized by ultraviolet light or an electron beam. 
     In a third embodiment of the present invention, anhydrides are added to the first component which is then mixed with the second component to form a solid or liquid composition which thermosets upon heating. 
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Generally 
     The present invention is directed to a series of new solventless polymeric compositions which can be applied as films, coatings or paints by rolling, brushing or spraying, or can be poured into substrates or molds to form void free solid castings. 
     The compositions comprise mixtures of amines, acrylates, epoxides, carboxylic acids, and anhydrides which are mixed together in predetermined amounts and orders so as to allow the reactants to react by an addition polymerization mechanism to form ladder-like structures. 
     In one embodiment of the invention, the components of the polymeric composition are formulated so as to form two liquid components which have a relatively low viscosity and can be separately stored for a year or more. When the two components are mixed together, they form a liquid composition which thermosets at ambient temperatures within a few hours without having to heat the composition. As used herein, ambient temperatures generally refers to temperatures between about 40° F. and 90° F. However, systems within the scope of the present invention will also set at higher and lower temperatures depending upon their viscosities and reactivities. 
     Because the components and the resulting mixture, for a short period of time, are liquids at ambient temperatures, the composition is easy to work with. Additionally, because the system is solventless, there are no solvents to evaporate and cause pollution or form blisters and voids in the final product. 
     In this embodiment, the first liquid component is formed from mono, di or polyamines, mixtures of mono, di or polyamines, or adducts of mono, di or polyamines with mono, di or polyacrylates or epoxides. The amount of acrylate or epoxide that must be added to the amine is dependent upon the actual compounds used. The basic requirement is that the component be a liquid of relatively low viscosity at ambient temperatures and have at least two reactive aminic hydrogens so that it can polymerize. Examples of suitable mixtures are more fully discussed hereinafter. 
     The second liquid component is formed from mono, di or polyacrylates, mixtures of mono, di or polyacrylates, or adducts of mono, di or polyacrylates with mono, di or polyfunctional epoxides and/or glycidyl ethers of acrylic acid or methacrylic acid. The amount of acrylates and epoxides in the second component is dependent upon the number of aminic hydrogens in the first component. If a fully cured system is desired, the number of acrylic linkages, that is, the number of acrylic C═C double bonds, and epoxides should be equal to the number of aminic hydrogens. If a photoprepolymer, as more fully discussed hereinafter, or a &#34;living&#34; polymer which can be further cured by ultraviolet light is desired, the number of acrylic linkages should exceed the number of aminic hydrogens. 
     In a second embodiment of the invention, mono, di or polyamines are mixed with mono, di or polyacrylates to form solventless photoprepolymers. The amines and acrylates are chosen and mixed such that there is an excess of acrylic linkages over aminic hydrogens. A photoinhibitor such as hydroquinone and a photoinitiator such as p,p&#39;dichlorobenzophenone are preferably added to the mixture. Because the amines react with the acrylates and epoxides to form tertiary amines, these photoprepolymers do not require the addition of additional photoaccelerators. 
     In a third embodiment of the invention, di or polyamines are mixed with mono or diacrylates followed by the addition of monofunctional anhydrides or carboxylic acidanhydrides and epoxides. These compositions form liquid or low melting solids which thermoset upon heating above about 140° C. through an addition polymerization. 
     The Reaction Components 
     The Amines 
     The useful amines of this invention are either individual members or classes of amines or their mixtures represented by the general structure R n  (NH 2 ) n . When n=1, the class of mono amines results having the general formula RNH 2  wherein R is a monovalent radical of aliphatic, cycloaliphatic, heterocyclic or aromatic structure and their combinations. Normally the R radical is composed of carbon and hydrogen atoms, but can also contain oxygen, sulfur, halogens (i.e., chlorine, bromine, fluorine, iodine) and their combinations in addition to carbon and hydrogen.

Cycloaliphatic diepoxides such as Bis-cyclohexane or Bismethyl cyclohexane adipate or glycolate diepoxides such as are manufactured by Union Carbide and CIBA-GEIGY Co. can also be used in the present invention. 
     ADDITION POLYMERIZATION MECHANISM 
     It was discovered that the addition polymerization of amines or hydrazine with acrylates are generally exothermic, and take place at ambient temperatures or below with the exception of aromatic amines. The rate of reaction is greater with primary than secondary amines. Also, hydrazine reacts faster than aliphatic primary diamines which in turn react faster than cycloaliphatic diamines, which in turn react faster than aromatic diamines with acrylates which in turn are more reactive than their methyl or alkyl substituted analogues. In fact, while aliphatic, cycloaliphatic, or heterocyclic amines react exothermically with acrylates and methyl acrylates at ambient temperatures, aromatic mono, di or poly amines usually have to be heated from about 100° to 160° C. for one to two hours in order to effect their addition polymerization. 
     The maximum stoichiometric addition of an amine and an acrylate involves the addition of all aminic hydrogen atoms to acrylate or methyl acrylate double bonds. For example, a secondary amine (imine) represented by the general structure ##STR1## wherein R, and R&#39; are monovalent radicals, reacts stoichiometrically with an acrylate represented by the general structure CH 2  ═CXY wherein X is equal to hydrogen, methyl, or an alkyl radical, and Y is equal to: ##STR2## 
     The following equations are illustrative of addition reactions between secondary amines (imines) and acrylates: ##STR3## R&#39; 2  equals --(CH 2 ) n--  or --(CH 2  CH 2  --O)n and --OR&#39; 2  O-- equals --NHCH 2  NH-- ##STR4## 
     A monomeric tertiary amine (n-1) acrylate. Wherein R,R&#39;,R 2 , R&#39; 2 , R 3  . . . R n  respectively are: mono, di, tri or poly valent radicals. 
     The replacement of an imine ##STR5## with a primary amine results when R&#39; equals H an leads to the following possibilities: ##STR6## 
     The replacement of a primary amine RNH 2  with a diimine having the structure R 2  (NHR) 2  leads to the following possibilities: ##STR7## 
     The replacement of a diimine with a primary diamine or hydrazine and their amine or hydrazine terminated diprimary amines or hydrazines rapidly increases their possibilities and their stochiometrical combinations, illustrated by the following examples: ##STR8## 
     (26) The case of (23) can be further reacted by diepoxides to form ladder like polymers as follows: ##STR9## 
     Equations 27(a) and 27(b) are based on exactly the same ingredients and molar ratios but due to the different sequence of addition, the final products are isomeric polymeric diacrylates. Equation 27(a) contains the mono acrylate linkages distributed on both nitrogen atoms and is a polymeric diimine. In the case of Equation 27(b) a polymeric amine containing two acrylate linkages on one nitrogen atom is formed. 
     These last two equations indicate how the manipulation of the sequence of addition results in isomeric products. Equation 27(a) results by allowing 1.0 mole of a diamine to react with 1.0 mole of a diacrylate until a high viscosity is obtained, and then adding it into 2.0 moles of diacrylate and mixing. Equation 27(b) results by slowly adding 1.0 mole of diamine to 3.0 moles of diacrylate under controlled conditions. 
     The following polytertiary amine octaacrylate gels very quickly, unless it is highly inhibited. ##STR10## 
     It was found that the addition reaction between mono, di or poly amines and mono, di or poly functional acrylates in the presence or absence of mono, di or poly functional epoxides are of a general nature and with the exception of aromatic amines, take place exothermically at ambient temperatures. Furthermore, it was found that the addition reaction between mono, di or poly amines and mono, di or poly functional acrylates, as well as the exothermic reactions of mono, di or poly amines with mono, di or poly epoxides proceeds faster with the acrylate reactants than with the epoxides. 
     Since mono, di or poly acrylates do not react with mono, di or poly epoxides, the addition reactions between mono, di or poly amines and mono, di or poly functional acrylates diluted with mono, di or poly epoxides predominantly proceeds, at first as an addition of aminic hydrogen atoms to acrylate bonds, and then the remaining aminic and iminic hydrogens add to the epoxide rings. Consequently, mono, di or poly acrylates can be used as solvents for mono, di or poly epoxides to significantly reduce their viscosities and both the solute and solvent enter into the addition polymerization reactions upon mixing with mono, di or poly amines. 
     Thus, although solid mono, di or poly amines or epoxides can also be used in the present invention, the criterion for solventless two component systems is that the resulting components A and B, after dilution with mono, di or poly functional acrylates should be liquids of relatively low viscosity. If the resulting components are solid, or very viscous liquids, they have to be diluted with inert solvents in order to reduce their viscosities to 1500 cps or below, but such systems are no longer solventless. 
     If the addition of mono, di or poly acrylates (or methyl acrylates) to mono, di or poly amines is in equivalent excess of at least one or more acrylate linkages over the iminic hydrogens, then the resulting liquid monomeric, oligomeric or polymeric compositions are novel photoprepolymers. Such photoprepolymers are stabilized by inhibiting them with up to 100 parts per million hydroquinone, ditertiary butyl hydroquinone, hydroxyl ethyl quinone or hydrobenzoquinone or other acrylate inhibitors to protect them from ultraviolet light and sunlight during storage. About 1% by weight of a photoinitiator such as p,p&#39; chlorobenzoquinone or hydroxybenzoketones is also added to the system. 
     Equation 23 above can be further reacted with mono anhydrides or carboxylic acid anhydrides in the presence of liquid mono, di or poly epoxides to produce liquid or low melting solid one component systems. Thus, clear, pigmented or filled solventless molding powders or liquids thermosetting upon heating at above 150° C. are obtained. 
     It was found that primary or secondary amines react faster with mono anydrides or carboxylic acid anhydrides than with diepoxides at ambient temperatures. For example, 2n moles of a diamine represented by the general formula H 2  N--R 2  --NH 2  and 2n moles of diacrylate represented by the general formula ##STR11## Addition of the above to 4n moles of methyl tetrahydrophthalic anhydride in the presence of 4 to 5 epoxide equivalents results in: ##STR12## (wherein Z 2  is equal to ##STR13## 
     Upon heating at above 150° C. the ##STR14## groups adds to oxiran or epoxide rings ##STR15## to form ##STR16## (hydroxy ester) linkages. 
     Also, it was found that the addition of 1 to 6%, or more, by weight to the component B composed of mono, di or poly acrylates, glycidyl esters of acrylic or methyl acrylic acids and/or mono, di or poly epoxides in their clear or pigmented form, of phenols, cresols, xylenols, naphthols, dihydroxy benzenes, dihydroxy naphthalenes, bisphenols and their mono or poly halo, nitro, ether, ester, alkyl, oxo, thio and sulfone substituted derivatives, isomers and homologues, followed by the equivalent mixing of component A and B catalyzes their poly addition reactions and significantly reduces their thermosetting times. Thus, by using a suitable catalyst it is possible to react aromatic amines with acrylates at ambient temperatures rather than having to heat the mixture. 
     The addition of phenolic catalysts provides fast thermosetting times for equivalent mixtures of components A and B of the clear or pigmented solventless systems, thus causing a shorter pot life for the mixture. The most practical utilization of these precatalyzed solventless, two component systems is with airless (or air) dual guns which provide minimum mixing times. 
     APPLICATIONS 
     Liquid solventless, two component systems of relatively low viscosity, which upon mixing thermoset at ambient temperatures through addition polymerization mechanisms proceeding in a &#34;ladder&#34; type formation yield compact, transparent, glossy and void free films or parts of any desired shape and thickness and are suitable for many applications. The use of air or airless spraying guns equipped with metering devices, ultrasonic mixing devices and pumping systems automatically mix only the specifically recommended ratios needed for spraying. If brushing is chosen with a solventless system as the method of application, the two components, A and B, should be well mixed for at least five minutes and then applied. Since there is no solvent evaporation there are minimal brushing marks resulting from constant changes in viscosity through evaporation of solvents. Additionally, from about one to three weight percent of a surface tension reducer such as hexakis methoxy methylene melamine can be added to the system. 
     It was also found that the clear or the lightly filled form of the system provides 100% active varnishes, lacquers, or sealants of any desired thickness having 92% or better transparency of liquid consistency. The relatively low viscosity and high gloss of the solventless two component systems make them particularly useful in producing solar panels, and in casting optical devices and gyroscopes. Aluminum or copper water conduits also can be readily cast into place as integral parts of a solar panel. 
     Furthermore, the solventless, liquid two component systems of this invention can be applied as paints of various shades and thicknesses. It was found that one coat can provide thicknesses of up to 10 mils while providing outstanding gloss, non-yellowing characteristics and excellent ultraviolet light, salt water and chemical resistance. Suggested applications of such paints are in marine, maintenance, construction, vessel, automotive and aircraft industries. 
     The paints are tough through the combination of hardness greater than H-7 and impact (direct or reverse) resistance greater than 190 lbs/sq. in. When filled with 30 to 75% by weight fiberglass or fiber cloth, or carbon fiber they can replace unsaturated polyesters or epoxides in producing reinforced plastics for boats, tanks, corrugated sheets, bowling balls, bowling alleys, trays and chairs. 
     It was found that the solventless, liquid, two component systems of this invention can be mixed with up to 90% by weight silicon dioxide, alone or in combination with minor quantities of pigments or dyes to produce pliable plaster-like putties which set to ceramic like materials upon curing at ambient temperatures. Suggested applications are water and oil pipes, tiles, prefabricated buildings, highway light reflectors, oil platform coverage, industrial floors, fishing lures, etc. In other words, the solventless, liquid, two component system can be used either as clear pigmented or filled coatings and paints as well as liquid thermosetting polymers for coating or molding objects of any shape, size or dimension. 
     Furthermore, it was found that the liquid solventless, two component systems have outstanding adhesion to glass, bricks, ceramics, all metals including stainless steel, iron, aluminum, copper, titanium, chrome, tin, zinc, all thermosetting and thermoplastic polymers with the exception of polyolefins and polytetrafluorines. These latter polymers can be used as molds for the two component system of the present invention. Furthermore, since the solventless, two component systems of this invention are compatible (act as solvents) for liquid or solid asphalts, they can be used to form solventless polyacrylate epoxide tars containing from 2 to 98% by weight asphalt for clear, pigmented or filled systems. In addition to asphalts, other hydrocarbon resins such as alpha polymethylstyrene, polyvinyl carbazole, and polyterpenes can be used with the liquid solventless system of this invention. Other applications involve solventless adhesives for wood, Formica, glass, metals, polyvinyl chloride pipes, polystyrene, ABS plastics, ceramics, leathers, fabrics, metals, paper and their combinations. The main applications of these photoprepolymers which are one component liquid, clear or filled systems are in the construction of printed electrical circuits and photoresists. 
     Other applications will become apparent by the specific illustrative examples given below. 
     EXAMPLES 
    
    
     EXAMPLE 1 
     In an 800 ml. glass beaker were placed 2.0 moles (420 grams) of methylene bis cyclohexane diamine (PAMC-20, a product of Du Pont Co.) and 16 grams of hexakis methoxy, methylene melamine also known as CYMEL-301 (a product of American Cyanamide Co.). To this mixture were slowly added over a period of 15 minutes 0.442 moles (100 grams) of 1,6 hexamethylene diol diacrylate under continuous mixing, and water cooling, which continued for an additional 30 minutes. The resulting product was an adduct of PAMC-20 and 1,6 hexamethylene diol diacrylate, diluted with PAMC-20 and CYMEL-301, consisting of 0.442 moles of adduct, 1.116 moles of PAMC-20 and 16 grams of CYMEL-301. The adduct comprises the 2/1 molar addition to the acrylic double bonds of 1,6 hexamethylene diol diacrylate and proceeds exothermically at ambient or lower temperatures. 
     Separately, in another 2000 ml. glass beaker were mixed 720 grams (4.0 epoxide equivalents) of EPON-826 with 1.558 moles (352 grams) of 1,6 hexamethylene diol diacrylate. 
     The first mixture had a viscosity of about 230 centipoise (cps) at ambient temperature and for convenience was called component A, while the second mixture had a viscosity of 188 cps at ambient temperature and was named for convenience component B. The total weight of component A was equal to 420+16+100=536 grams, while the weight of component B was equal to 720+352=1072. The individual components A and B are stable in storage at ambient temperatures for periods in excess of one year without any significant change in viscosity. 
     The mixing stochiometrical weight ratio of component A to component B is equal to 536/1072=1/2. The mixing of 10 grams of component A with 20 grams of component B results in a liquid having an initial viscosity of about 200 cps which rapidly increases with time. However, this particular formulation has 50 to 60 minutes of pot life at ambient temperatures. Upon mixing component A with component B at a weight ratio of 1/2, the resulting mixture increases in viscosity as a function of time and finally solidifies within a few hours to a highly transparent, colorless, glossy, tough and void free film or part. The solidification process is a function of time and temperature and independent of thickness or size. Increased temperatures rapidly accellerate solidification, while decreased temperatures lower the rate of the mixture&#39;s solidification. 
     The involved chemical reactions proceed exothermically and apparently in the following order. First, the poly addition of the 2n moles of diamine (PAMC-20) and its adduct with the 2n moles of the diacrylate of 1,6 hexamethylene diol to form a polymeric imine-acrylate. Second, the polymeric imine-acrylate enters into another addition polymerization reaction with the 4n epoxide equivalents, resulting in a ladder like type formation. The steps can be described schematically as follows: ##STR17## 
     Wherein R 2 , R&#39; 2  and Z 2  are divalent radicals corresponding in Step 1 and Step 2 to the specific structures of: ##STR18## 
     The CYMEL-301 is 1% by weight of the total weights of components A and B and does not participate in any reaction, but it was found to significantly reduce surface tension and improve film characteristics. Thicker films have much less surface tension and do not require CYMEL-301. 
     EXAMPLE 2 
     In an 800 ml. glass beaker were placed 1.5 moles (174 grams) of 1,6 hexamethylene diamine and through a dropping funnel were added to it, under stirring and cooling 1.5 moles (381 grams) of 1,6 hexamethylene diol dimethyl acrylate to form a viscous polyimine-dimethylacrylate, designated component A. Separately component B was formed by simply mixing 1.5 moles (453 grams) of tetraoxoethylene glycol diacrylate and 10 grams of CYMEL-301. Component B had a viscosity of about 90 cps at ambient temperatures. The mixing ratio of component A to component B by weight is equal to A/B=555/463=1.2/1.0. 
     To 12 grams of component A were added 10 grams of component B and mixed for five minutes, then 146 grams of silicon dioxide (sand flour) and 3 grams of chrome green oxide were added to this mixture under continuous mixing. The pliable, plastic semisolid product was placed in aluminum cups and became solidified at ambient temperature within 4 hours. The final product was a hard, solid, green, glossy and smooth composite containing 87% by weight silicon dioxide. When this composite was exposed to an open flame it did not burn due to the 87% silicon dioxide content. It is believed that such composites based on components A and B of most of the following examples containing silicon dioxide, magnesium oxide, aluminum oxide, antimony oxides, and their like, are stronger than cement, and can be used in prefabricated houses or buildings. 
     Such composites also allow reinforcement with steel, and offer a variety of color choices, as well as heat and water insulation. Additionally, they do not shrink or expand significantly, and therefore do not crack. At less than 1/8 of the equivalent concrete thickness, they have excellent impact resistance and elminate the need for plastering, painting, insulation, water proofing and maintenance. Water, oil and gas piping of any diameter or wall thickness can also be made from these compositions. 
     EXAMPLE 3 
     In an 800 ml. glass beaker were placed 2.0 moles (420 grams) of PAMC-20, 1.0 mole (136 grams) of meta xylylene diamine, 1.0 mole (185 grams) of lauryl (or dodecyl) amine and 29.0 grams of CYMEL-301 and mixed for 10 minutes to form component A. Separately in another glass beaker were placed 7.0 epoxide equivalents (1260 grams) of EPON-828, 2.0 moles (424 grams) of neopentyl glycol diacrylate and 1.0 mole (296 grams) of trimethylol propane triacrylate, mixed for about 10 minutes and labeled component B. The stochiometrical weight ratio of component A and B in this case is A/B=770/1980=1/2.57. 
     In a high speed blender were placed 100 grams of component A, 305 grams titanium dioxide (Rutile type), 0.5 grams ultramarine blue and grinded for 15 minutes. Then 257 grams of component B were added and mixed for an additional 5 minutes. The resulting mixture was sprayed to bonderized steel panels in layers having thicknesses varying from 3 to 300 mils. The panels dried to touch within 3 hours and dried hard after 6 hours. Gloss was greater than 90% at a 60 degree angle. Direct and reverse impact resistance was greater than 190 psi. These steel panels were found to have excellent resistance to nitric acid, seawater and ultraviolet light, as well as outstanding gloss retention, all of which is attributed to the polyacrylate structure. 
     In another experiment, castings were made in metallic molds coated with carnauba wax or polyethylene boxes. These castings were more than 2 inches thick and solidified within 6 hours at ambient temperature or within 10 minutes at 130° C. These castings were highly transparent and tough. 
     EXAMPLE 4 
     In a 1500 ml. glass beaker were placed 30 grams Cymel-301, 1.0 mole (152 grams) N,N&#39;, methylene diacrylamide and 2.0 moles (426 grams) of tetradecyl amine and mixed until the exotherm ceased, thus forming a diiminediimide. Then 2.0 moles (420 grams) of PAMC-20, 1.0 mole (136 grams) of metaxylene diamine and 1.0 mole (116 grams) of Amine-6 were added and mixed for 5 minutes to form component A. 
     Component B was formed in another 3000 ml glass beaker by mixing 18 epoxide equivalents (1440 grams) of EPON-828, 2.0 moles (424 grams) of neopoentyl glycol diacrylate, and 0.67 moles (198 grams) of trimethylol propane triacrylate. The stochiometrical mixing weight ratio of component A to component B is equal to A/B=1167/2062=1/1.77. When components A and B are mixed together they form polyimine acrylate at first which add to epoxides and form three dimensional polyhydroxyl tertiary amine-epoxy-propionates and N-substituted acrylamides. 
     It should be noted that instead of 0.67 moles of trimethylol propane triacrylate, 1.0 mole could be used to temporarily decrease cross-linking density to form a photoprepolymer. Further cross-linking can be promoted later through the use of an ultraviolet light. 
     Furthermore, the 1.0 moles of 1,6 hexamethylene diol diacrylate and the 2.0 moles neopentyl glycol diacrylate could have been replaced by 2.0 or 3.0 moles of trimethylol propane triacrylate. In the case of 2.0 moles of trimethylol propane triacrylate the cross-linking rate and density are rapidly increased, providing less pot life for the mixed system but faster setting at ambient temperatures. In the case of 3.0 moles of trimethylol propane triacrylate the pot life is typical of the other systems, but cross-linking continues after its application through the unreacted acrylic bond, for months or years by the ultraviolet light provided by the sun. In other words, it behaves like a &#34;living&#34; crosslinked polymer. 
     In another test, 20.62 grams of component B were mixed with 270 grams asphalt having a melting point of about 60° C. To this mixture were added 11.67 grams of component A, mixed for 5 minutes, and then 900 grams of silicone dioxide were added to the mixture, mixed and poured into concrete holes. After 3 hours the final composite was hard, and inspection of it several months later indicated no signs of cracking. 
     EXAMPLE 5 
     In an 800 ml. glass beaker were placed 0.5 epoxide equivalents (90 grams) of EPON-826 and 2.25 moles (462.5  grams) of PAMC-20, 8.0 grams of CYMEL-301 and mixed for 15minutes to form component A. In another 1500 ml. glass beaker were placed 4 epoxide equivalents (700 grams) of Novolac-431, 2.0 moles (424 grams) of neopentyl glycol diacrylate, and mixed for 10 minutes to form component B. The mixing ratio of this solventless system of component A to component B is A/B=561/1124=1/2. 
     Ten grams of component A were mixed with 7.5 grams of zinc oxide and 2.5 grams of red oxide. To this mixture were added 20 grams of component B, mixed for an additional 5 minutes and then the mixture was applied to panels of wood, concrete, steel, aluminum, tin and glass to yield solventless thermosetting, glossy paints at ambient temperatures, even in the absence of titanium dioxide and grinding of the pigments. 
     EXAMPLE 6 
     In an 800 ml. glass beaker were placed 0.5 moles (300 grams) of Jeffamine D-600 and was called component A. In another 800 ml. glass beaker were placed one epoxide equivalent (175 grams) of Novolac-439, 0.35 moles (125 grams) of pentaerythritol tetra acrylate and mixed for 15 minutes to form component B. The mixing stochiometrical weight ratio of component A to component B for this system is equal to A/B=1/1. 
     The thermosetting solid polymer resulting from the mixing of equal parts of component A to B is a &#34;living&#34; one, because of the total 0.35×4=1.4 acrylic linkages, only 1.0 of them were added to amine, leaving 0.4 out of 1.4 or about 28.6% free to polymerize over any period of time with the sun&#39;s ultraviolet light. The long chain linkages of the final product also provide excellent flexibility and resiliency, which is maintained at very low temperatures. 
     EXAMPLE 7 
     In an 800 ml. glass beaker were placed 1.0 mole (403 grams) of Jeffamine T-403, which is polyoxopropylene triamine, and to it were added 1.0 mole (53 grams) of acrylonitrile, under mixing and cooling with water to form component A. Separately in another 1000 ml. glass beaker were placed 3.0 epoxide equivalents (540 grams) of EPON-826, 1.0 mole (330 grams) of tetraethylene glycol dimethyl acrylate, 13 grams of CYMEL-301 and mixed for 15 minutes to form component B. The mixing weight ratio of A/B=456/883=1/1.94. 10 grams of component A were mixed with 19.4 grams of component B to form an excellent adhesive for glass, steel and wood. 
     EXAMPLE 8 
     Component A was made by mixing in a glass beaker 0.5 moles (500 grams) of Jeffamine D-1000 and 0.25 moles (8 grams) of hydrazine. Component B was made in another beaker by mixing 1.5 epoxide equivalents (270 grams) of EPON-826 with 0.50 moles (127.9 grams) of 1,6 hexamethylene diol dimethyl acrylate and 0.125 moles (44 grams) of pentaerythritol tetraacrylate. The mixing ratio of component A to component B of this system is A/B=508/442=1.15/1. 
     When 11.5 grams of component A are mixed with 10 grams of component B they react to form cross-linked polyhydroxyl tertiary (amine and hydrazine) epoxy-acrylates. 
     EXAMPLE 9 
     Component A was made by placing in an 800 ml. glass beaker 1.0 mole (403 grams) Jeffamine T-403, 12.5 grams of CYMEL-301, and slowly adding to it 0.25 moles (82.5 grams) of tetraoxoethylene glycol dimethyl acrylate. Component B was made in another beaker by mixing 3.0 epoxide equivalents (540 grams) of EPON-826 and 1.25 moles (272.25 grams) of 1,6 hexamethylene diol diacrylate. The weight ratio of component A to component B of this system is A/B=1/1.63. 
     Ten grams of component A were mixed with 16.3 grams of component B to form six batches and 11, 24.6, 26.7, 40.5, 55.6, and 106.8 grams of chopped glass fiber or fiber cloth were respectively added to the batches. The resulting mixtures were pressed in polyethylene molds to form castings consisting of 30/70, 40/60, 42/58, 60/40, 70/30 and 80/20 glass to resin ratios. 
     Similar castings were made with general purpose unsaturated polyesters cured with ketone hydroperoxides as well as with EPON-828 and Versamides (amino-terminated polyamides based on dimer fatty acid and triethylene tetra amine condensates). Straight comparisons between all of these specimens measured by impact resistance and resilience suggests that the solventless liquid system of the present invention was better than the epoxide-Versamide 1 and unsaturated polyesters. Based on these findings, as well as in the outstanding adhesion of the solventless system to glass, it will be apparent to those skilled in the art that the solventless systems of this invention are especially adaptable for use as binders for reinforced plastics used in the construction of yachts, storage tanks, pipes, corrugated sheets, fishing lures, bowling balls, etc. Additionally, bridge or construction columns of better strength seem to be feasible. In addition to glass fibers, other filler materials such as graphite, Kevlar or metallic fibers can be also used. 
     EXAMPLE 10 
     In an 800 ml. glass beaker were placed 1.0 mole (60 grams) of ethylene diamine, 1.0 mole (216 grams) of azelaic hydrazide, and under mixing and cooling were added 0.8 moles (203.2 grams) of 1,6, N,N&#39; dimethyl hexamethylene diol diacrylate. Two hours later 0.4 moles (28.4 grams) of acrylamide were added and mixed for additional 30 minutes to form component A, having an oligomeric polyamine-hydrazide amide ester structure, and an amine equivalent of 84.6. Component B was formed by using 2 epoxide equivalents (360 grams) of EPON-826 diluted with 2.0 moles (284 grams) of glycidyl ester of methyl acrylic acid and 11 grams of CYMEL-301. The mixing equivalent weight ratio of component A to B is equal to 507.6/655=0.77/1. 
     When 7.7 grams of component A are mixed with 10 grams of component B they form cross-linked polyhydroxyl tertiary (amine and hydrazine) epoxy acrylates. 
     EXAMPLE 11 
     In a 2000 ml. glass beaker were placed 2.0 moles (232 grams) of Amine-6, 0.5 moles (165 grams) of oxotetraethylene diol dimethyl acrylate, 1.0 mole (152 grams) of N,N&#39; methylene diacrylamide, 23 grams of CYMEL-301 and mixed to form component A. Component B was formed by mixing 2.5 moles (565 grams) of 1,6 hexamethylene diol diacrylate and 6.0 epoxide equivalents (1080 grams) of EPON-828, or simply using 5.0 moles (710 grams) of glycidyl ester of methyl acrylic acid acrylate, or 5 moles (1130 grams) of 1,6 hexamethylene diol diacrylate or their combined mixtures. 
     As is shown in this example it is possible to vary the ratios and the ingredients of component B or A to achieve desired viscosities, ratios and properties. 
     EXAMPLE 12 
     Component A was formed by mixing 0.5 moles (410 grams) of dimer fatty acid condensate (which was formed from the reaction of 1.0 mole (564 grams) dimer fatty acid with 2.0 moles (292 grams) of triethylene tetramine), 2.5 moles (388 grams) of trimethyl 1,6 hexamethylene diamine and 32 grams of CYMEL-301. Similarly, component B was made by mixing 8 epoxide equivalents (1440 grams) of DOW-431 Novolac, 2.0 moles (452 grams) of 1,6 hexamethylene diol diacrylate and 1.0 mole (302 grams) of oxotetraethylene diacrylate. The equivalent weight ratio of component A and B are A/B=830/2194=1/2.64. 
     When 10 grams of component A are mixed with 26.4 grams of component B they form polyhydroxyl amides-tertiary-amine-epoxy-acrylates. 
     Similarly, component A was made by mixing 1.0 mole (592 grams) of dimer fatty hydrazide, 3.0 moles (630 grams) of PAMC-20, 33 grams of CYMEL-301 and 0.5 epoxide equivalent (90 grams) of EPON-828 at ambient temperatures. Component B was prepared by mixing 7.5 epoxide equivalents (1350 grams) of EPON-828 dissolved in 4.0 moles (848 grams) of neopentyl glycol diacrylate. The equivalent weight ratio of component A to component B is equal to A/B=1345/2198=1/1.63. 
     Ten grams of component A were mixed with 16.3 grams of component B and a thin layer of this was applied to bond together two pieces of wood. The next day significant force was used to take apart the two wooden pieces, and it was found that all the fibers of the bonded wooden surface were totally removed suggesting that the adhesive bond was much stronger than wood. Similarly impressive results were obtained by adhering tiles, bricks, concrete, steel, glass, polyvinyl chloride, polycarbonate, polyesters, epoxide and polystyrene pieces as individual and combined pieces. The absence of solvents in the present invention provides a compact continuous bond while low viscosity penetrates the substrate thus resulting in outstanding adhesion. 
     EXAMPLE 13 
     In a 1000 ml. glass beaker were placed 3.0 moles (430 grams) of PAMC-20, and 1.0 mole (213 grams) of tetradecyl amine and 32 grams CYMEL-301 and mixed for 20 minutes to form component A. Separately, in another glass beaker were mixed 7 epoxide equivalents (1260 grams) of EPON-826, 2.0 moles (424 grams) of 1,6 hexamethylene diol diacrylate, 1.0 mole (296 grams) trimethylol propane triacrylate and 92 grams of ortho cresol to form component B. The mixing ratio of component A to component B was A/B=875/2100=1/2.4 and the ortho cresol catalyst was 4.38% by weight of component B and 3.1% by weight of the combination of components A and B. 
     Upon mixing 10 grams of component A with 24 grams of B a rapid increase in viscosity occurs within 15 minutes and the mixture thermosets to touch free in 40 minutes. 
     In another experiment the ortho cresol was replaced with phenol, chloro phenol, nonyl phenol, ortho dinitro cresol, para dinitro cresol, hydroquinone, dibutyl hydroquinone and Bisphenol-A. It was observed that the thermosetting time of component A and mixtures was decreased as the acidity and the quantity of phenolic compound used increased. Accelleration of thermosetting time at ambient temperatures shortens the pot life of the mixed components A and B and it becomes impractical for brushing applications; however, it is efficient and practical when a dual mixing spray gun is utilized which will limit mixing time of component A and B to a satisfactorily short period of time. 
     EXAMPLE 14 
     In a 1000 ml. glass beaker were placed 3.0 moles (630 grams) of PAMC-20, 1.0 mole (213 grams) of tetradecyl amine and 32 grams of CYMEL-301 and mixed for 30 minutes to form component A. Separately, in another glass beaker, were mixed 7 epoxide equivalents (1260 grams) of EPON-828, 2.0 moles (452 grams) of 1,6 hexamethylene diol diacrylate, 1.0 mole (296 grams) of trimethylol propane triacrylate and 1100 grams of ortho dinitrocresol to form component B. The mixing ratio of component A to B was A/B=875/3108=1/3.55. 
     This was sprayed by using a dual, airless gun to form a fast, thermosetting, yellow, solventless varnish. 
     The same experiment was repeated by using 875 grams of component A which were mixed with 1197 grams titanium dioxide and 3108 grams of component B. This mixture was sprayed by an airless gun to form an antifouling paint which thermoset in less than 50 minutes. 
     EXAMPLE 15 
     In a 2000 ml. glass beaker were placed 1.0 mole (136 grams) of meta xylylene diamine, 0.67 grams of hydroquinone inhibitor, and to it were added under constant mixing 4.0 moles (1208 grams) of oxotetraethylene glycol diacrylate under continuous stirring for about 2 hours to form a photoprepolymer, which after the addition of 13.4 grams (1% by weight) of p,p&#39; dichlorobenzoquinone photoinitiator was stored in dark-colored bottles at ambient temperatures. It should be noted that the photoprepolymers of this invention do not require addition of photo accellerators such as tertiary amines inasmuch as they are already built into the molecule. 
     Clear or lightly filled with silica flour solutions of this photoprepolymer were poured in aluminum cups to form layers 2 to 4 mils thick. When exposed to ultraviolet light, these solutions thermoset within a few seconds at ambient temperatures to form clear, transparent and resilient films. The same experiment was repeated by using 1.0 mole (116 grams) of Amine-6 and 3.0 moles (678 grams) of 1,6 hexamethylene diol diacrylate and gave similar results. 
     EXAMPLE 16 
     In an 800 ml. glass beaker were placed 1.0 mole (213 grams) tetradecylamine, 0.256 grams of monohydroxyl ethylene hydroquinone inhibitor, 1.0 mole (296 grams) of trimethylol propane triacrylate, and mixed for about two Phours. This was followed by the addition of 5.13 grams of p,p&#39; dichlorobenzoquinone photointiator to form a photoprepolymer, which was stored in a dark container at ambient temperatures. Thin, clear or lightly filled films of this solution alone or as a mixture with mono or polyfunctional acrylates thermoset upon exposure for a few seconds to ultraviolet or electron beam light. 
     EXAMPLE 17 
     In an 800 ml. glass beaker were placed 1.0 mole (105 grams) of diethanol amine, 0.2 grams of ditertiary butyl hydroquinone inhibitor, 1.0 mole (296 grams) of trimethylol propane triacrylate. The solution was mixed for about two hours, followed by the addition of 4 grams of p,p&#39; dichlorobenzophenone to form a difunctional photoprepolymer. When films of this photoprepolymer were exposed to ultraviolet light they were cross-linked to form polyhydroxyl tertiary amine saturated acrylates through the photo addition polymerization of the acrylic linkages. 
     The same experiment was repeated by replacing the 1.0 mole of trimethylol propane triacrylate with 1.0 mole of pentaerythritol tetra acrylate to form a trifunctional acrylate. Again, after the addition of 1% by weight of photoinitiator and in the absence of any photo accellerator these photoprepolymers thermoset upon exposure for a few seconds to ultraviolet light or electron beam. 
     EXAMPLE 18 
     In an 800 ml. glass beaker were placed 1.0 mole (144 grams) of 1,6 N,N&#39; dimethyl hexamethylene diamine, 0.4 grams of hydroquinone inhibitor, 2.0 moles (604 grams) of tetraoxoethylene diol diacrylate. The solution was mixed for about two hours followed by the addition of 7.5 grams p,p&#39; dichlorobenzoquinone photoinitiator to form a tertiary amine diacrylate photoprepolymer having a molecular weight of 748. This photoprepolymer was converted by UV light to a cross-linked polyamine saturated acrylate through the photo addition of the acrylic linkages. 
     The same experiment was repeated by replacing the 1.0 mole of 1,6 N,N&#39; dimethyl hexamethylene diamine with the adducts of 1.0 mole of Amine-6 to 2.0 moles of acrylonitrile or 1.0 mole of PAMC-20 to 2.0 moles of acrylamide and the partial or total replacement of the 2.0 moles of oxotetraethylene diol diacrylate with neopentyl glycol diacrylate, butylene diol diacrylate, or 1,6 hexamethylene diol diacrylate. Again these photoprepolymers, after the addition of 1% by weight of photoinitiator and in the absence of any photoaccellerator, thermoset upon exposure for a few seconds to ultraviolet light or electron beam. 
     EXAMPLE 19 
     In a 3000 ml. glass beaker were placed 2.0 moles (232 grams) of Amine-6, 2.0 moles (632 grams) of tetraoxoethylene dimethyl acrylate and mixed at ambient temperatures for about 3 hours until an extremely viscous material was developed. Under cooling and continuous mixing were added 4.0 moles (616 grams) of hexahydrophthalic anhydride, diluted with 5 equivalents (730 grams) of dimethylcyclohexamethylene diepoxide glycolate and mixed at ambient temperatures to form a homogenous semi-solid polyester, N-substituted amide carboxylic acid mixture in a cycloaliphatic liquid diepoxide. This system is one component, solventless, and stable on storage at ambient temperatures, thermosetting upon heating at about 150° C. through an addition polymerization involving the opening of the epoxide ring with the carboxylic group. Each epoxide equivalent corresponds to 0.8 or 1.0 carboxylic groups and the reason that 1/0.8 ratios can be used in that the hydroxy groups formed from the epoxide ring opening react with other epoxide groups to form hydroxyl ethers. 
     The same experiement was repeated by replacing the 2.0 moles of Amine-6 with 2.0 moles (420 grams) of PAMC-20, while leaving the other components unchanged. 300 grams of the low melting poly-oxo-ester N-substituted hexahydrophthalamide carboxylic acid, cycloaliphatic diepoxide were mixed with 2100 grams of aluminum trihydrate under heating at about 90° C. to fluidize and homogenize the final mixture, which upon cooling was solidified and grinded to a fine powder. Heating of this powder at above 150° C. for at least 30 minutes thermoset to form a composite having outstanding tracking resistance to high voltage, as a result of combining the aluminum trihydrate with a totally saturated cycloaliphatic structure. 
     The same experiments were repeated by using phthalic, succinic, docecenyl succinic, maleic or trimellic anhydride instead of hexahyddrophthalic anhydride and Novolac DOW-431 instead of cycloaliphatic diepoxide. Instead of aluminum trihydrate, oxides of zinc, iron, magnesium, antimon, the dioxides of titanium, silicon and chrome green oxide were used to form powder, solventless paints polymerizable by an addition polymerization upon heating at about 150° C. However, optimum non-tracking properties are only obtained from the combination of saturated structures in combination with aluminum trihydrate. Aromatic structures are considered unsaturated in non-tracking applications, and are less suitable for high voltage applications. 
     EXAMPLE 20 
     Several monoamines were synthesized by using a 2.0 liter glass resin kettle equipped with a mechanical stirrer, a thermocouple connected to a temperature recorder, a water trap, a vertical condenser and a heating mantle. 
     Flexible liquid imide monoamines were made by using the following combinations: 2.0 moles (296 grams) phthalic anydride added slowly to 1.0 mole (403 grams) of Jeffamine T-403 and then heated up to 180° C. until 2.0 moles (36 grams) of water were collected. The resulting product was a bis-phthalimide polyoxopropylene amine having a molecular weight of 663. Similarly, 2.0 moles (536 grams of dodecyl succinic anhydride were reacted with 1.0 mole (403 grams) of Jeffamine T-403 to form a diimide primary amine was formed. Using 1.0 mole tetrahydrophthalic anhydride, 1.0 mole pelargonic acid and 1.0 mole of Jeffamine T-403, an amide-imide primary amine. The reaction of 1.0 mole (60 grams) urea with 1.0 mole (61 grams) mono ethanol amine results in 1.0 mole monoethanol urea through the elimination of 1.0 mole of gaseous ammonia, which upon further reaction with 1.0 mole (230 grams) of Jeffamine-230 through the elimination of 1.0 mole of gaseous ammonia results in 1.0 mole of hydroxyl ethyl urea polyoxopropylene amine, having a molecular weight of 317. 
     Other imide or amide mono primary amines can be formed from the condensation of 1.0 mole of succinic anhydride and Jeffamine D-400 (an oxopropylene diamine) through the elimination of 1.0 mole of water. Instead of succinic, anhydride, other anhydrides such as methyl hexahydrophthalic, maleic, glutaric, or itaconic anhydrides can be used. Instead of Jeffamine-230, trimethyl hexamethylene diamine, isophorone diamine, PAMC-20 or meta xylene diamine can be used in a 1/1 molar ratio with mono anhydrides to form mono imide primary amines. Monocarboxylic acids, such as formic, acetic, 2-ethyl hexanoic, lauric, stearic, oleic, furoic, benzoic, or their methyl esters can be condensed in 1/1 molar ratio with ethylene diamine, 1,6 hexamethylene diamine, 1,6 trimethyl hexamethylene diamine, isophorone diamine, PAMC-20, Jeffamines (230, 400, 600, 800, 1000 and 2000) to form mono amide amines that are useful as ingredients as such or as their mixtures in the component A of the solventless two component system. 
     Also, the reaction of 1.0 mole (135 grams) of sulfonyl dichloride with 1.0 mole (169 grams) of diphenyl imine, followed by the addition of 1.0 mole of Jeffamine D-400 results in a sulfonyl amide-amine having a molecular weight of 633. An example of hydrazide amine was produced by adding 1.0 mole (50 grams) of hydrazine monohydrate to 1.0 mole (214 grams) of methyl ester of lauric acid at ambient temperature and azeotroping the water and methanol with cyclohexane. The resulting hydrazine amine has a molecular weight of 214. 
     Another dihydrazide mono amine is obtained by reacting 1.0 mole (176 grams) of the dihydrazide of adipic acid with 1.0 mole (298 grams) methyl ester of stearic acid until 32 grams of methanol were removed. 
     EXAMPLE 21 
     In a two liter resin kettle were placed 1.0 mole (166 grams) of terephthalic acid, 1.0 mole (146 grams of) phthalic anhydride and 2.0 moles of polyoxopropylene diamine-400 (Jeffamine D-400) and heated to 180° C. until 3.0 moles (54 grams) of water were condensed. Heat was turned off and the final product was a mono primary amine, imidediamide. 
     The same experiment was repeated by placing 2.0 moles (420 grams) of PAMC-20 with 1.0 mole (60 grams) of urea to form a urea diamine having a molecular weight of 446. Also, at ambient temperature to 90° C., 2.0 moles (460 grams) of polyoxopropylene diamine-230 (Jeffamine D-230) with 1.0 mole (146 grams) of diethyl oxalate were reacted to form an oxalamide diamine having a molecular weight of 514. Replacement of the 2.0 moles (460 grams) Jeffamine D-230 with 2.0 moles (806 grams) polyoxotriamine-400 (Jeffamine T-403) and 1.0 mole diethyl oxalate results in an oxalamide tetramine having a molecular weight of 860. 
     In the same resin kettle were placed 3.0 moles (474 grams) 1,6 trimethyl hexamethylene diamine, and 2.0 moles (376 grams) of azelaic acid and heated up to 200° C. until 4.0 moles of water were removed and a diamine terminated oligomeric poly-amide having an average molecular weight of 769 was formed. Similarly, other diamines or polyamine terminated compositions were prepared from the condensation reaction between the following: 1.0 mole of sebacic acid with 2.0 moles of 1,6 hexamethylene diamine, 1.0 mole of adipic acid with 2.0 moles of trimethyl 1,6 hexamethylene diamine, 1.0 mole of azelaic acid with 2.0 moles of diethylene triamine and 1.0 mole of dimer fatty acid with 2.0 moles of triethylene tetraamine. Also, 1.0 mole of sulfonyl chloride was condensed with 2.0 moles of trimethyl, 1,6 hexamethylene diamine, PAMC-20 or polyoxopropylene diamine-400 to form amide or sulfonamide diamines. All of the amine terminated compounds alone, or as mixtures with simple mono, di or poly amines, can be used as the main ingredient in preparing the component A of the liquid solventless system. 
     EXAMPLE 22 
     A liquid and low melting mono hydrazide was made by mixing 1.0 mole (242 grams) of the methyl ester of tetradecanoic acid, 1.0 mole (50 grams) of hydrazine monohydrate, and heating the mixture up to 90° C. to remove 1.0 mole of methanol and 1.0 mole of water to form the monohydrazide of tetradecanoic acid. 
     Dihydrazides were also made from the condensation reactions between 1.0 mole of the dimethyl esters of sebacic acid, dodecenedioic acid, or dimer fatty acid and 2.0 moles of hydrazine through the elimination of 2.0 moles of methanol. 
     A trihydrazide was also made from the condensation of 1.0 mole of trimer fatty acid with 3.0 moles of hydrazine. 
     These mono, di or tri hydrazides readily react at ambient temperatures with mono, di or poly functional acrylates, epoxides, or glycidyl ester methyl acrylic acid. They can be used alone or with simple amines as the main ingredients to form component A of the solventless system. It was found that hydrazide and oxalamide linkages further enhance the chemical and mechanical performance properties of the thermoset solventless system. 
     EXAMPLE 23 
     In a two liter resin kettle equipped with a mechanical stirrer, a thermocouple connected to a temperature recorder and a vertical condenser attached to a polyethylene tube ending in a water container were placed 8 moles (928 grams) of 2-methyl, 1,5 pentamethylene diamine and 4.0 moles (240 grams) of urea. This mixture was heated for 5 hours at a temperature between 120° C. and 180° C. under continuous stirring until 8 moles (136 grams) of gaseous ammonia were evolved. The resulting product was N&#39;,N&#39; bis 2-methyl, 1,5 pentamethylene diamine urea having a molecular weight of 258. 
     Component A was formed by mixing 1.0 mole (213 grams) of tetradecyl amine and 1.0 mole (296 grams) of trimethylolpropane triacrylate for about one hour at ambient temperatures to form a tertiary amine linear polyacrylate to which was then added 1.5 moles (387 grams) of N&#39;,N&#39; bis 1,5 pentamethylene diamine urea.

Under continuous mixing and cooling 5.0 moles (500 grams) of ethyl acrylate were slowly added over a period of about 2 hours. The temperature was then raised to 160°-180° C. and maintained untitl 5.0 moles (230 grams) of ethyl alcohol were collected. The resulting compound was a triamine-monoamide composed of two primary and one secondary amino groups having a molecular weight of 286 and an amine value of 57.2. The compound is beta 2-methyl 1,5 pentane diamine of propionamido, 2 methyl pentane amine-1.
