Description: MORPHOLINO END-CAPPED, HINDERED AMINE SUBSTITUTED AMINOTRIAZINE AND THEIR USE AS LIGHT STABILIZERS BACKGROUND OF THE INVENTION Field of the Invention This invention relates generally to novel morpholino end-capped, hindered amine substituted aminotriazines and the use thereof as a hindered amine light stabilizer. 0 This application claims priority of co-pending U.S. Provisional Application Serial No. 60/067.730 filed December 8, 1997. Description of Related Art it is well known that sunlight and other sources of ultraviolet light radiation cause 5 degradation of polymers as evidenced by the embrittlement or yellowing of plastic articles made therefrom. It is also well known that this degradation can be inhibited by use of light stabilizers incorporated in or on such articles. The reaction products of 2-substituted-4,6-dihalo-1 ,3,5-triazines and α,ω-diamines that have a 2,2,6,6-tetraalkyl-4-piperidinyl group on the nitrogen atoms thereof, are in 0 general known as ultraviolet light stabilizers. It is believed that amino-1 ,3-5-triazines that bear such 2,2,6,6-tetraalkyl-4-piperidinyl groups function as free radical scavengers. Disclosures of a number of such "polyamino-1 ,3,5-triazines" can be found in the following publications, ail of which are incorporated by reference herein for ail purposes as if fully set forth: US4086204, US4331586, US5021485, US5047531 , US5130429, US5416215, EP- 5 A-0357223, EP-A-0309400, EP-A-0309401 , EP-A-0309402, EP-A-0377324, EP-A- 0569334, EP-A-0690094, EP-A-0723990, CA-A-2167660 and JP-A-63196654. Typically, ultraviolet light stabilizers and in particular, polyamino-1 ,3,5-triazines, are blended or co-extruded with polymeric materials that are subject to exposure to various levels of ultraviolet radiation. 0 Certain known polyamino-1 ,3,5-triazines can exhibit high viscosity even at elevated temperatures. Due to their inherently high viscosity problems, these certain polyamino- 1 ,3,5-triazines require high processing temperatures which can result in thermal degradation of the polyamino-1 ,3,5-triazine or polymer into which the polyamino-1 ,3,5- triazine is incorporated, as well as long term wear and tear on processing equipment, 5 resulting in added maintenance and/or replacement costs. Accordingly, polyamino-1 ,3,5- triazines that have relatively lower processing temperatures, while at the same time are capable of functioning as effective free-radical scavengers, would be highly desirable. SUMMARY OF THE INVENTION The present invention provides a new class of polyamino-1 ,3,5-triazine ultraviolet light stabilizers which bear cyciohexylamino groups pendant from the triazine ring, and which are end-capped with a morpholino group. More specifically, the new polyamino-1 ,3,5- triazines of the present invention, useful as ultraviolet light stabilizing agents, have the following general formula (I): wherein R 1 is selected from hydrogen, hydrocarbyl, hydrocarbyloxy and a group of the formula (II) each R 2 is independently selected from hydrogen, oxyl, hydroxy, hydrocarbyl and hydrocarbyloxy; each R 3 is independently selected from an alkyl of 1 to 5 carbon atoms; each of R 4 and R 5 is independently a hydrocarbyl group; n is 2-12; and x is 1-50, characterized in that each R 4 is a morpholino group, and each R 5 is a cyclohexyl group. These polyamino-1 ,3,5-triazines may be prepared by reacting cyclohexylamine with a 2,4,6-trihalocyanurate, preferably, cyanuric chloride, and preferably in the presence of base, to afford a 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine; the 2,6-dihalo-4- cyclohexylamino-1 ,3,5-triazine being reacted with an Λ/,Λ/ -bis(2,2,6,6-tetramethyl-4- piperidinyl)- ,α>-(C 2 -C 12 )alkylenediamine, preferably in the presence of a base, to afford a polyamino-1 ,3,5-triazine; the polyamino-1 ,3,5-triazine being reacted with morpholine to afford the present cyclohexylamine substituted, morpholino end-capped polyamino-1 ,3,5- triazines. Further preferred process details are disclosed below. The new polyamino-1 ,3,5-triazines of the present invention are particularly useful as ultraviolet light stabilizing agents for use in stabilizing a wide variety of organic substrates such as generally disclosed in the previously incorporated references including, for example, thermoplastic and crosslinked polymers such as polyesters, polyethers, polyurethanes, polystyrenes, high-impact polystyrenes, and preferably, polyolefins, used particularly as films, monofiliments, multifiliment yarns, coating matrices, and the like. The present invention, consequently, also relates to a method for stabilizing an organic material, e.g., a thermoplastic substrate, by incorporating into such organic material the inventive polyamino-1 ,3,5-triazines in an amount effective to stabilize the organic material against the effects of actinic radiation, and the organic material so stabilized. These and other features and advantages of the present invention will be more readily understood by those of ordinary skill in the art from a reading of the following detailed description. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The Novel Polyamino-1.3.5-Triazines As indicated above, the polyamino-1 ,3,5-triazines in accordance with the present invention are compounds of the above general formula (I). The term "hydrocarbyl" in the context of the present invention, and in the above formulas, broadly refers to a monovalent hydrocarbon group in which the valency is derived by abstraction of a hydrogen from a carbon atom. Hydrocarbyl includes, for example, aliphatics (straight and branched chain), cycloaliphatics, aromatics and mixed character groups (e.g., aralkyi and alkaryl). Hydrocarbyl also includes such groups with internal unsaturation and activated unsaturation. More specifically, hydrocarbyl includes (but is not limited to) such groups as alkyl, cycloalkyl, aryl, aralkyi, alkaryl, alkenyl, cycloalkenyl and alkynyl, preferably having up to 24 carbon atoms. A hydrocarbyl may optionally contain a carbonyl group or groups (which is/are included in the carbon count) and/or a heteroatom or heteroatoms (such as at least one oxygen, sulfur, nitrogen or silicon), in the chain or ring. The term "hydrocarbyloxy" in the context of the present invention means hydrocarbyl -O-. The term "hydrocarboyl" as used herein means hydrocarbyl-co-. In preferred embodiments, R 1 is hydrogen or group (II) depicted above and, more preferably group (II). In preferred embodiments, each R 2 is independently selected hydrogen, hydrocarbyl and hydrocarbyloxy and, more preferably, from hydrogen, an alkyl of 1 to 4 carbon atoms, and alkoxy of 1 to 4 carbon atoms, and an acetyl group. In preferred embodiments, each R 3 is methyl. In preferred embodiments, n is 4-8 and especially 6, and x is 1-20 and especially 1- 15. Finally, further preferred embodiments may include any combination of parameters mentioned above. Methods of Preparation In general, the polyamino-1 ,3,5-triazines of the present invention can be prepared by the methods generally described in the previously incorporated references. In a preferred process, a 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine is reacted with an N,N -bis(2,2,6,6-tetraalkyl-4-piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine having the following formulas: wherein Hal is a halogen preferably selected from Cl, Br and I, and especially Cl; and R 2 and R 3 are as defined above, under conditions to prepare a monomeric/oligomeric/polymeric intermediate terminated by Hal and/or hydrogens, then reacting (end-capping) this intermediate with morpholine to prepare the polyamino-1 ,3,5-triazine of the present invention. The 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine depicted above is typically obtained by reacting a 2,4,6-trihalocyanurate with cyclohexylamine in an amount sufficient to provide a 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine with less than 25% combined yield of di- and tri-substituted side products. Such 2,4,6-trihalocyanurates can be obtained commercially, or by methods known to those skilled in the art. Preferably, the molar ratio of cyclohexylamine to the 2,4,6-trihalocyanurate is about 0.89:1 to about 1.10:1 , more preferably about 0.95:1 to about 1.05:1 , and most preferably about 1.01 :1. In a preferred embodiment, the 2,4,6-trihalocyanurate is cyanuric chloride. The reaction between the 2,4,6-trihalocyanurate and cyclohexylamine can occur in monophasic solution in an organic solvent including, but not limited to, methylene chloride, chloroform, carbon tetrachloride, tetrahydrofuran, diethyl ether, ethyl acetate, benzene, toluene, xylenes, and the like, preferably in the presence of an organic and/or inorganic base. As suitable organic bases may be mentioned organic amines such as pyridine, 4- dimethylaminopyridine, triethylamine, ethyl diisopropylamine, 1 ,8- diazabicyclo(5.4.0)undec-7-ene, 1 ,5-diazabicyclo(4.3.0)non-5-ene, 1 ,4- diazabicyclo(2.2.2)octane, N,N,N',N'-1 ,8-bis(dimethylamino)naphthalene and the like, and mixtures thereof. As suitable inorganic bases may be mentioned alkali metal hydroxides, alkali metal carbonates or bicarbonates, and alkaline earth carbonates, as well as mixtures thereof. Mixtures of organic and inorganic bases may also be utilized. Preferably, however, the reaction between the 2,4,6-trihalocyanurate and cyclohexylamine occurs in a biphasic mixture of an organic solvent and water, the organic solvent being methylene chloride, chloroform, carbon tetrachloride, benzene, toluene, xylenes, or the like, and further in the presence of an organic and/or a inorganic base, such as those mentioned above. In either the monophasic or biphasic system, the preferred base is an inorganic base and especially sodium hydroxide, which is preferably utilized in a molar ratio of base to the 2,4,6-trihalocyanurate is about 0.92:1 to about 1.15:1 , and more preferably about 0.99:1 to about 1.08:1 , and especially at a slight molar excess (such as 1.01 :1). Molar ratios for other bases would typically be similar to sodium hydroxide, adjusted for the number of base equivalents per mole. In the biphasic system, an inorganic base can conveniently be employed as an aqueous solution, preferably at about 10% to about 60%, more preferably at about 40% to about 60%, and most preferably at about 50%, weight/weight. In a preferred embodiment, the reaction between the 2,4,6-trihalocyanurate and cyclohexylamine occurs in a biphasic mixture of toluene and water, and in the presence of sodium hydroxide. In this preferred embodiment, the sodium hydroxide is employed as a 50% (weight/weight) aqueous solution. Generally, the ratio (w/w) of organic solvent to the 2,4,6-trihalocyanurate is about 1 :1 to about 10:1 , preferably about 2.3:1 to about 3:1. Where the reaction between the 2,4,6- trihalocyanurate and cyclohexylamine occurs in a biphasic mixture of an organic solvent and water, the ratio (w/w) of the organic solvent to the overall water content is about 3:1 to about 1.5:1 , preferably about 2.0:1 to about 1.5:1. Typically, the cyclohexylamine is added to a mixture of the 2,4,6-trihalocyanurate and the organic solvent, and at a rate such that the reaction temperature remains at between about -5°C to about 15°C, preferably at between about 0°C to about 10°C. To the resulting mixture is then added the base, preferably sodium hydroxide, at a rate such that the reaction temperature remains at between about -5°C to about 15°C, preferably at between about 0°C to about 10°C, affording a predominant amount of the desired 2,6- dihalo-4-cyclohexylamino-1 ,3,5-triazine intermediate. As indicated above, the preferred 2,4,6-trihalocyanurate is cyanuric chloride, meaning that the resulting desired 2,6-dihalo-4- cyclohexylamino-1 ,3,5-triazine is 2,6-dichloro-4-cyclohexylamino-1 ,3,5-triazine. It is to be pointed out that along with the 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine, small amounts of 2-halo-4,6-bis(cyclohexylamino)-1 ,3,5-triazine and 2,4,6- tris(cyclohexylamino)-1 ,3,5-triazine side products may also be formed. If desired, such side products can be removed via known techniques such as selective recrystallization. The 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine intermediate is then admixed, at a temperature of about 50°C to about 100°C, preferably at about 70°C to about 80°C, with the Λ/,Λ/ -bis(2,2,6,6-tetramethyl-4-piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine depicted above, to provide the polyamino-1 ,3,5-triazine in accordance with the present invention. The N,N -bis(2,2,6,6-tetramethyl-4-piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine can be obtained by means well-known to those of ordinary skill in the art, such as disclosed in Example 2 of previously incorporated US4104248. Preferably, such is obtained by reacting about 2 eq. of 2,2,6,6-tetramethyl-4-piperidone with about 1 eq. of an α,ω-(C 2 - C 12 )alkylenediamine to afford a corresponding bis(imine), and reducing the bis(imine) with, for example, H 2 in the presence of PtO 2 , to afford the N,N -bis(2,2,6,6-tetramethyl-4- piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine. If it is desired that the N,N -bis(2,2,6,6-tetramethyl-4-piperidinyl)-α,ω-(C 2 - C 12 )alkylenediamine be substituted at one or both of piperidyl nitrogen atoms, it can be modified, for example, by methylation according to the procedures detailed in previously incorporated US5130429 (see Example 1 , part b); by alkoxylation according to the procedures detailed in previously incorporated EP-A-0569334 (see Example 1); and by oxylation according to the procedures detailed in previously incorporated US5416215 (see Example 2). The reaction between the 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine and the N,N - bis(2,2,6,6-tetramethyl-4-piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine advantageously proceeds in the presence of a base, such as the inorganic and/or organic bases described above. Preferred is an inorganic base, particularly an alkali metal carbonate, and especially sodium carbonate. The inorganic bases can be solvated with the aid of water. In such a case, the ratio (w/w) of water to the 2,4,6-trihalocyanurate (used in preparing the 2,6-dihalo-4- cyclohexylamino-1 ,3,5-triazine intermediate) is in the range of from about 1.05:1 to about 1.10:1. The molar ratio of N,N -bis(2,2,6,6-tetramethyl-4-piperidinyl)-α,ω-(C 2 - C 12 )alkylenediamine to the 2,4,6-trihalocyanurate (used in preparing the 2,6-dihalo-4- cyclohexylamino-1 ,3,5-triazine intermediate) is preferably in the range of from about 0.5:1 to about 1.5:1 , and more preferably from about 0.8:1 to about 1.2:1. The molar ratio of the preferred inorganic base (sodium carbonate, to the 2,4,6-trihalocyanurate (used in preparing the 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine intermediate) is about 0.8:1 to about 1.2:1 , preferably about 1 :1. Molar ratios for other bases can be readily determined by adjusting for the number of base equivalents per mole. The mixture containing the 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine intermediate, the N,N -bis(2,2,6,6-tetramethyl-4-piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine and the base is heated at a temperature of from about 50°C to about the reflux temperature of the organic solvent(s) used in the process. Preferably, a biphasic mixture of toluene and water, such as used in the initial reaction between the 2,4,6-trihalocyanurate and cyclohexylamine, and the above mixture is heated at a temperature and for a time so as to form a monomeric/oligomeric/polymeric mixture of products containing 1-30, and preferably 1-20, repeat units while removing water and toluene by distillation as a water/toluene azeotrope. Depending on solvent choice, this reaction temperature will typically be in the range of from about 90°C to about 105°C, preferably at about 98°C to about 102°C. Once the water/toluene azeotrope begins to distill from the reaction mixture, the reaction mixture is heated for about 30 minutes to about 48 hours, preferably for about 4 to about 24 hours. To this reaction mixture is then added morpholine, so as to end cap the product to ultimately form the polyamino-1 ,3,5-triazines of the present invention (wherein the R 4 groups are morpholino). The molar ratio of morpholine to the 2,4,6-trihalocyanurate (used in the preparation of the 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine intermediate) is typically about 0.10:1 to about 1.5:1 , and preferably about 0.5:1 to about 0.7:1. Optionally, and preferably, the morpholine may be added to the reaction mixture in conjunction with an organic solvent such as one described above, or a mixture of organic solvents. If it is desired that an organic solvent is added in conjunction with the morpholine, the ratio (w/w) of organic solvent to the 2,4,6-trihalocyanurate (used in the preparation of the 2,6-dihalo-4-cyclohexylamino-1 ,3,5-triazine intermediate) is about 1 :1 to about 1.5:1. Following the addition of morpholine, and optionally the organic solvent, the reaction mixture is heated, preferably at the reflux temperature of the reaction mixture, typically for about 15 minutes to about 6 hours, and preferably for about 30 minutes to about 2 hours, so as to facilitate morpholine end-capping and achieve the desired end product. Advantageously, the resulting product is treated with a base, such as an organic and/or inorganic base described above, and preferably sodium hydroxide. The addition of such a base acts as a scavenger for any residual hydrogen halide by-product from the reaction between the 2,4,6-trihalocyanurate and the N,N -bis(2,2,6,6-tetramethyl-4- piperidinyl)-α,ω-(C 2 -C 12 )alkylenediamine, as well as ensure that the polyamino-1 ,3,5- triazine exists in its free-base form. When employed, this additional base is conveniently an aqueous solution, preferably at a concentration of from about 10% to about 60%, more preferably at about 40% to about 60%, weight/weight, and is added in a molar ratio, for the preferred base sodium hydroxide, relative to the amount of 2,4,6-trihalocyanurate originally used in the reaction, of about 0.3:1 to about 0.5:1. Following addition of the base, the reaction mixture can be heated, preferably at its reflux temperature, typically for about 15 minutes to about 6 hours, and preferably for about 30 minutes to about 2 hours. If an aqueous base is used in any of the above steps, the resulting reaction mixture will be biphasic, with the polyamino-1 ,3,5-triazine residing in the organic phase. To recover the polyamino-1 ,3,5-triazine, the aqueous phase is removed and discarded, and the remaining organic phase is concentrated, preferably in vacuo, to provide the polyamino-1 ,3,5-triazine of the present invention. If desired, the resulting product can be further purified by solvent/non-solvent precipitation techniques well known to those skilled in the art. Stabilizer Composition From the above process discussion, it is evident that the resulting polyamino-1 ,3,5- triazine product will actually be a mixture of various monomeric, oligomeric and/or polymeric species, for example, where R 1 is predominantly hydrogen or the substituted triazine group, and x is preferably in the range of from 1 to 30. These stabilizer composition products, comprising a mixture of compounds of the formula (I), also form a part of the present invention. Preferably, such mixtures possess a number average molecular weight (M n ) of from about 1200 to about 3000, and more preferably from about 1500 to about 2500, and a weight average molecular weight (M of from about 2000 to about 5500, and more preferably from about 2400 to about 4500, as measured by high performance size exclusion chromatography (HPSEC).

The polyamino-1 ,3,5-triazines of the present invention may be used in widely varying amounts in such applications depending upon such things as the material to be stabilized and the particular application. However, when employed as a stabilizing additive for materials such as organic polymers, the polyamino-1 ,3,5-triazines of the present invention are typically employed in amounts from about 0.01 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and most preferably from about 0.1 to about 5% by weight, based on the weight of the material to be stabilized. As examples of preferred polymers may be mentioned thermoplastic polymers such as polyolefins and/or polymers comprising heteroatoms in the main chain. Preferred polymers are also thermoplastic polymers comprising nitrogen, oxygen and/or sulphur, especially nitrogen or oxygen, in the main chain. Also of interest are compositions in which the polymer is a polyolefin, for example polyethylene or polypropylene. Incorporation into the thermoplastic polymers can be carried out by addition of the polyamino-1 ,3,5-triazine compounds and any further additives by the methods conventional in the art. The incorporation can expediently be made before or during shaping, for example by mixing the pulverulent components or by adding the stabilizer to the melt or solution of the polymer, or by applying the dissolved or dispersed compounds to the polymer, with or without subsequent evaporation of the solvent. Elastomers can also be stabilized as lattices. The polyamino-1 ,3,5-triazines can also be added to the polymers to be stabilized in the form of a masterbatch which comprises these compounds, for example, in a concentration of from about 2.5 to about 25%, preferably from about 5 to about 20% by weight of the polymer. These polyamino-1 ,3,5-triazines can expediently be incorporated into the polymeric material by any number of methods, including those conventionally employed in the art, including by, for example: a) as an emulsion or dispersion (for example to lattices or emulsion polymers); (b) as a dry mix during mixing of additional components or polymer mixtures; (c) by direct addition to the processing equipment (for example extruders, internal mixers, etc.); or (d) as a solution or melt. The stabilized polymer compositions obtained in this way can be converted into shaped articles, for example fibers, films, tapes, sheets, sandwich boards, containers, pipes and other profiles, by any number of conventional methods, for example hot pressing, spinning, extrusion, roto-molding or injection molding. Therefore, the present invention additionally relates to the use of the polymer composition according to the invention for the production of a shaped article. Depending upon their ultimate end use, the polyaminol-1 ,3,5-triazines of the present invention may be combined with a variety of additives conventionally employed in the stabilizing art.

As indicated above, the polyamino-1 ,3,5-triazines of the present invention may be incorporated into a substrate, e.g., an organic material to be light stabilized, by any of the known techniques for compounding additives. For example, the polyamino-1 ,3,5-triazines and optionally an additive may be compounded by dry blending with the substrate in powder or granular form, followed by milling, Banbury mixing, molding, casting, extruding, swelling and the like. Alternatively, the polyamino-1 ,3,5-triazines may be added, as a solution or a slurry in a suitable inert solvent, or dispersant, to the substrate in powder or granular form, the whole mixed intimately in a mixer, and the solvent subsequently removed. As a further possibility, the polyamino-1 ,3,5-triazines may be added to the substrate during the preparation of the latter, for instance at the latex stage of polymer production, to provide prestabilized polymer material. The polyamino-1 ,3,5-triazines of the present invention are suitable for the photochemical stabilization of substrates such as undyed, dyed or printed fiber materials comprising for example, silk, leather, wool, polyamide or polyurethanes, and especially cellulose-containing fiber materials of all kinds. Examples of such fiber materials are the natural cellulose fibers, such as cotton, linen, jute and hemp, and also viscose staple fiber and regenerated cellulose. Preferred textile fiber materials are those of cotton. The polyamino-1 ,3,5-triazines are also suitable for the photochemical stabilization of hydroxyl- containing fibers in blend fabrics, for example blends of cotton with polyester fibers or polyamide fibers. To this end, the polyamino-1 ,3,5-triazine is applied to the textile fiber material by one of the customary dyeing methods, advantageously in a quantity of about 0.01 to about 5% by weight, preferably about 0.1 to about 3% by weight and, in particular, from about 0.25 to about 2% by weight, based on the weight of the fiber material. The polyamino-1 ,3,5-triazines can be applied to the fiber material in various ways and fixed on the fiber, especially in the form of aqueous dispersions or printing pastes. The textile fiber materials finished with the polyamino-1 ,3,5-triazines possess improved protection against photochemical breakdown of the fiber and yellowing phenomena, and, in the case of dyed fibre material, are of enhanced (hot) light fastness. Processing Advantages The polyamino-1 ,3,5-triazines of the present invention have improved, i.e., lower, processing temperatures and accordingly, lower viscosities, than known cyciohexylamino end-capped polyamino-1 ,3,5-triazine light stabilizers, such as those disclosed in previously incorporated EP-A-0357223. As a result, the polyamino-1 ,3,5-triazines of formula (I) have the added advantage in that their processing, in particular, their coextrusion or admixture with polymer substrates sought to be light stabilized, requires less heat than for the processing of known cyciohexylamino end-capped polyamino-1 ,3,5-triazine light stabilizers, which results in minimized thermal degradation of the substrate, as well as an increase in the lifetime of processing equipment and an overall savings in energy and manufacturing costs. The present invention will be illustrated by reference to the following examples, which are by way of exemplification and not limitation. Example 1 Preparation of a Morpholino End-Capped Polyamino-1.3.5-Triazine To a 0°C mixture of 18.54 g (101 mmol) of cyanuric chloride in 52 mL of toluene and 24 mL of water was added 9.97 g (101 mmol) of cyclohexylamine, at a rate such that the temperature of the resulting mixture was maintained at 0 to 10 °C. To the resulting mixture was added 8.30 g (104 mmol) of a 50% aqueous solution of NaOH, at a rate such that the temperature of the resulting mixture was maintained at 0 to 10 °C. The resulting mixture was then added to a mixture of 35.46 g (90 mmol) of N,N -bis(2,2,6,6-tetramethyl- 4-piperidinyl)-1 ,6-hexanediamine, 10.53 g (99 mmol) of sodium carbonate and 20 mL of water at 75 °C, and heated so as to remove, via distillation, water and toluene as a water/toluene azeotrope until a temperature of 98-102°C was achieved. Following removal of the azeotrope, the reaction mixture was heated at reflux for a total of 13 hours from the addition of the triazine mixture to the diamine mixture. After this reflux period, 6.83 g (78 mmol) of morpholine and 25 mL of toluene were added, and the resulting mixture was heated at reflux for 1 h. Then, 3.24 g (40.6 mmol) of a 50% aqueous solution of NaOH, followed by 50 mL of toluene, were added, and the resulting mixture was allowed to heat at reflux for an additional hour. After cooling to room temperature, the lower, aqueous phase was removed, and the upper, organic phase was filtered and concentrated in vacuo Xo afford a morpholino end-capped polyamino-1 ,3,5-triazine product in accordance with the present invention. The resulting product was found, by HPSEC, to possess an M n of 2070 and an M w of 3630. Example 2 Viscosity Comparison I. Preparation of Morpholino End-Capped Polyamino-1 ,3,5-Triazine Step 1. To a 250 mL 3-neck round bottom flask, equipped with an overhead stirrer, condenser and thermometer, were charged 26 mL of water and 46 mL of toluene, which was cooled to less than 3°C using an ice/water bath. 20 g of cyanuric chloride (0.109 moles) was then charged into the flask all at once. 10.8 g of cyclohexylamine (0.109 moles) was then slowly added to the flask at a rate so as to keep the temperature below 10°C, followed by 8.95 g of a 50 wt% aqueous sodium hydroxide solution (0.112 moles) which was also slowly added as a rate so as to keep the temperature below 10°C. The resulting mixture was stirred for 15 minutes at a temperature between 1 ° and 3°C. Step 2. While the above reaction was in progress, a 500 mL 3-neck round-bottomed flask, equipped with an overhead stirrer, fraction-cutting distillation head and thermocouple, was charged with 38.3 g of N,N'-bis(2,2,6,6-tetramethyl-4-piperidinyl)-1 ,6- hexanediamine (0.097 moles), 11.4 g of sodium carbonate (0.108 moles) and 22 mL of water. This mixture was heated to 70°C and the reaction mixture from Step 1 was charged to this flask all at once. The mixture was heated to reflux while distilling off the toluene/water azeotrope until a temperature of 101 °C was achieved. At this point, 9.5 mL of water and 44 mL of toluene had been distilled off, and the distilling head was switched to total reflux. Reflux was continued for a total time of 13 hours from the addition of the reaction mixture from Step 1. 100 mL of toluene was then added, producing a milky-white mixture, which was cooled to less than 80°C and split into two equal 105 mL portions. Step 3. One of these portions was heated was heated to 97-100°C, and 3.7 g of morpholine (0.043 moles) and 13.4 mL of toluene were added. Stirring was continued for one hour at 95-100°C. 1.75 g of a 50 wt% aqueous sodium hydroxide solution, 27 mL of toluene and 3 mL of water were then added, and the heating and stirring continued for an additional 1 hour. The temperature was then brought to 80°C and the mixture allowed to settle for 30 minutes, after which the aqueous phase was split off. The remaining organic portion was dried azeotropically using a Dean-Stark trap. 2.0 g of celite filter aid was added and the product filtered and stripped of toluene to yield 31 g of a clear amber solid. Analysis of this product yielded the following results: NMR (CDCI 3 , 300 MHZ): δθ.81 t, J=12 Hz, 0.5H; (δ1.10s; 51.13 br s, 9H combined); δ1.18s, 1.6H; δ1.27 br s, 11 H; δ1.4-1.77 br m, 6.7H; δ1.9-2.1 br m, 1.5H; δ1.83 dd, J=3, 12 Hz, 0.5H; δ2.63 t, J=7.5 Hz, 0.3H; δ2.87 t br t, J=11.5 Hz, 0.2H; δ3.26 br m, 2H; (δ3.67 br s; δ3.74 br m, 3.2H combined); δ4.44 br m, 0.3H; δ4.58 d, J=7.5 Hz, 0.4H; δ5.0-5.4 br m, 1.0H. HPSEC M n 2070 M„ 3630. II. Preparation of First Cyciohexylamino End-Capped Polyamino-1 ,3,5-Triazine Step 3 above was repeated for the second 105 mL portion except that the morpholine was replaced with 4.24 g of cyclohexylamine (0.043 moles). Filtration and solvent strip yielded 21 g of a clear amber solid. Analysis by HPSEC surprisingly revealed an M n of 2850, indicating a significantly different molecular weight profile, rendering the product unsuitable for a comparative viscosity testing against the above morpholino end-capped product. III. Preparation of Second Cyciohexylamino End-Capped Polyamino-1 ,3,5-Triazine In order to prepare a cyciohexylamino end-capped product of a similar molecular weight profile for comparison purposes, Steps 1 and 2 above were repeated in their entirety except that an aliquot of the product of Step 2 was taken after 10 hours of reaction (as opposed to 13 hours of reaction). This product was reacted with cyclohexylamine by the procedure as set forth above, resulting in a product possessing an M n of 2100 and an M w 3590 (as determined by HPSEC). IV. Viscosity Comparison Both the morpholino end-capped and the second cyciohexylamino end-capped products were measured for complex viscosity with the aid of a RMS 605 mechanical spectrometer (Rheometric Scientific Inc.) in the dynamic mode. The test parameters were as follows: Parallel plates: 25.0 mm or 50.0 mm depending on viscosity Strain: sinusoidal with angular frequency of 10 radians/s Gap: 1-2 mm Temperature ramp: 5°C/min. Time/measure: 30 s Atmosphere: nitrogen. The strains were adjusted to keep torques between 2-20 g/cm. Sample preparation: The samples, in the form of fine granules, were placed on the lower plate of the rheometer and the temperature raised to form a bubble-free melt. Contact was then made with the upper plate and the sample temperature was allowed to drop until a stiff viscous liquid was attained. Time was allowed for temperature equilibrium, then the gap was set and measurements started. The results are presented in the table below. As can be seen, the morpholino end- capped product in accordance with the present invention possessed a significant and surprisingly lower viscosity than the comparative cyciohexylamino end-capped product.
