Abstract:
Organopolysiloxane sheet or tube polymers are made by contacting a sheet or tube silicate with an alkenyl group containing chlorosilane to form an alkenylsiloxy polymer, and subsequently contacting the alkenylsiloxy sheet or tube polymer with a hydrosilane or hydrosiloxane in the presence of a hydrosilation catalyst, to catalyze a reaction between the alkenyl group on the alkenylsiloxy polymer and hydride functionality on the hydrosilane or hydrosiloxane. Silylalkoxysiloxane sheet or tube polymers are made by contacting a sheet or tube silicate with an acidic solution of an alkenyl alcohol to form a polymeric sheet or tube alkenyloxysiloxane, and subsequently contacting the alkenyloxysiloxane with a hydrosilane or hydrosiloxane in the presence of a hydrosilation catalyst, to catalyze a reaction between the alkenyl group on the alkenyloxysiloxane and hydride functionality on the hydrosilane or hydrosiloxane.

Description:
BACKGROUND OF THE INVENTION 
     This invention is directed to silicone compounds, and methods of making silicate-based sheet and tube type siloxane polymers. 
     Silicones are made from silica by reducing it in an electric furnace to silicon metal, i.e. 
     
         SiO.sub.2 +2 C→Si+2 CO 
    
     The silicon metal is treated with RCl, typically methyl chloride, in the &#34;Direct Process&#34;, as the basis of commercial production, i.e. 
     
         Si+2 RCl→R.sub.2 SiCl.sub.2 
    
     Hydrolysis of the organochlorosilanes gives siloxane structures which are used in the manufacture of many silicone products, i.e. 
     
         nMe.sub.2 SiCl.sub.2 +2nH.sub.2 O→n[Me.sub.2 Si(OH).sub.2 ]+2nHCl→n[Me.sub.2 Si(OH).sub.2 ]→HO(Me.sub.2 SiO).sub.n H+(n-1) H.sub.2 O 
    
     Alternative routes to silicones involving the preparation of silicone polymers from silicate materials are embodied in U.S. Pat. No. 3,661,846 (May 9, 1972). This invention is an improvement and furtherance of the efforts described in the &#39;846 patent to find other unique approaches in the manufacture of silicones. 
     BRIEF SUMMARY OF THE INVENTION 
     One object of this invention is to provide new, simple, and versatile routes, to siloxane polymers having segments derived from silicate structures by using readily accessible starting materials, that in many cases, give nontoxic byproducts. Another object is to prepare distinctively shaped organosiloxanes, useful as additives in conventional amorphous silicone materials such as resins, fluids, and gums; and to create &#34;supramolecular&#34; structures that offer benefits in the areas of gels, cosmetics, rheological additives, greases, elastomers, sealants, fire resistant materials, and molecular reinforcement. 
     These and other objects of the invention will become apparent from a consideration of the detailed description. 
    
    
     DETAILED DESCRIPTION 
     The invention relates to the synthesis and characterization of copolymers having organosiloxane or organopolysiloxane segments and silicate derived segments, where the silicate derived segments have unique supramolecular structures such as tubular or sheet structures. The polymers are derived from naturally occurring or synthetic sheet silicates and synthetic tube silicates by a two-step process. 
     The first step consists of the reaction of a monofunctional silane that contains at least one unsaturated group with a sheet silicate or a tube silicate to produce a sheet-like or tube-like organosiloxane polymer. The organosilane is represented with the general formula RR&#39;R&#34;SiCl. 
     The sheet silicate apophyllite KFCa 4  Si 8  O 20 .8H 2  O is a commercially available crystalline mineral. It may be purchased from supply houses such as Ward&#39;s Natural Science Establishment, Rochester, N.Y. The tube silicate K 2  CuSi 4  O 10  is a synthetic material. Methods of preparing this synthetic silicate are described in various publications including U.S. Pat. No. 4,942,026 (Jul. 17, 1990); J. Polym. Prepr. (Am. Chem. Soc., Div. Polym. Chem.) 1991, 32(3), 508-509; and Colloids and Surfaces, 1992, 63, 139-149. 
     Below is a simplification of the first step of the process. 
     Scenario A 
     
         apophyllite sheet silicate+RR&#39;R&#34;SiCl→alkenylsiloxy sheet polymer 
    
     In the alkenyl (olefin) group containing chlorosilane RR&#39;R&#34;SiCl, the R&#39; and R&#34; groups are alkyl radicals with 1-6 carbon atoms, such as methyl, ethyl, propyl, butyl, pentyl, and hexyl; and R is an alkenyl radical with 1-16 but preferably 1-8 carbon atoms such as vinyl, allyl, hexenyl, and octenyl. Some representative olefin functional chlorosilanes are vinyldimethylchlorosilane, allyldimethylchlorosilane, 5-hex-1-enyldimethylchlorosilane, and 7-oct-1-enyldimethylchlorosilane. 
     In this reaction, the chlorine reacts directly or indirectly with cations (i.e. Ca 2+ ) of the silicate. 
     Some specific embodiments representative of Scenario A are shown below:

     The second step involves the controlled reaction of the unsaturated groups of the polymer formed in the first step with a hydrosilane or hydrosiloxane to produce another sheet organosiloxane polymer or another tube organosiloxane polymer. 
     The term hydrosilation applies to the addition of Si--H across any unsaturated species, i.e. 
     
         .tbd.SiH+CH.sub.2 ═CHSi.tbd.→.tbd.Si--CH.sub.2 CH.sub.2 --Si.tbd. or 
    
     
         .tbd.SiH+CH.sub.2 ═CHR→.tbd.Si--CH.sub.2 CH.sub.2 --R. 
    
     Silanes and siloxanes that contain a silicon bound hydrogen atom can add across the double bond. Typically, the reaction is conducted in the presence of a platinum catalyst or a catalyst which is a complex of platinum. 
     The degree of unsaturation of the final polymer is partly controlled by the type of starting hydrosilane or hydrosiloxane, and partly controlled by the type of intermediate polymer used. The intermediate and final layer polymers have increased inter-layer spacings over that of the starting minerals. The magnitude of spacing depends upon the size of the chlorosilane used in Step 1 and hydrosilane used in Step 2. 
     For example, apophyllite has an inter-layer d spacing of 8.7 Å, the vinyldimethylsiloxy apophyllite sheet polymer has an inter-layer d spacing of 16 Å based on powder X-ray Diffractomery (XRD), and the octenyldimethylsiloxy apophyllite polymer has an inter-layer d spacing of 24 Å. These differences can impact performance of the sheet and tube materials in their application as fillers, rheology modifiers, or molecular reinforcing agents for silicone fluids, elastomers, and resins. 
     The hydrosilation reaction of the intermediate polymer proceeds nearly quantitatively to produce the final polymer. In the final polymer, practically all unsaturated groups are silylated. Thus, the octenyldimethylsiloxy sheet polymer can be practically quantitatively hydrosilated with dimethylethoxysilane and with pentamethyldisiloxane using chloroplatinic acid as catalyst. The inter-layer spacing of the sheet polymers so produced increases to 27 Å and 35 Å, respectively. Fourier transform infrared spectroscopy confirms practically complete hydrosilation of the --C═C-- double bonds and formation of .tbd.Si--C.tbd. bonds. Similar hydrosilation of the octenyldimethylsiloxy sheet polymer with HMe 2  SiO(Me 2  SiO).sub.˜6 Me 2  SiH produces a final sheet polymer with an even larger inter-layer spacing 39 Å. 
     The hydrosilation reactions described herein are heterogeneous processes that take place on the surface of the intermediate sheet polymer, and are presumed to take place on the surface of the intermediate tube siloxanes. 
     These materials have potential and offer a variety of benefits in areas such as gels, cosmetics, rheological additives, greases, elastomers, sealants, fire resistant polymers, molecular reinforcement agents, and resins. Examples of some potential benefits are (A) gels with controlled rheological properties formed between silicone fluids and the intermediate or final polymers with various d spacings; (B) silicone resins molecularly reinforced by the exfoliation of the intermediate or final polymers; (C) supramolecular structures produced by tying up the intermediate or final polymers with reactive siloxane matrices (i.e., fluids, gums, or resins) utilizing hydrosilation, peroxide catalysis, or other curing process; and (D) control in permeability properties.

     The same second-step hydrosilation scenario is possible with potassium copper tube silicate derived organosiloxane polymers as shown below:

     Ideally, equivalent amounts of .tbd.Si--H containing reactant and unsaturated olefin group containing sheet or tube polymer reactant should be employed in the process, and one ethylenic linkage is the theoretical equivalent of one silicon bonded hydrogen atom. It may be necessary however to use an excess of the .tbd.SiH reactant to totally consume the unsaturated olefin group containing sheet or tube polymer reactant. 
     The maximum amount of platinum catalyst employed is determined by economical considerations, and the minimum amount by the type and purity of reactants employed. Very low concentrations of platinum catalyst such as 1×10 -10  moles of catalyst per equivalent of the olefin group containing sheet or tube polymer, may be used when the reactants are extremely pure. However, it is possible to use about 1×10 -8  moles catalyst per equivalent weight of sheet or tube polymer, and even 1×10 -7  to 5×10 -2  moles platinum catalyst, per equivalent weight of sheet or tube polymer. 
     &#34;Moles&#34; of platinum catalyst are measured in terms of one mole providing one unit atom (e.g. one gram atom) of platinum. An &#34;equivalent weight&#34; of olefin is the amount of reactant furnishing one unit weight of ethylenic unsaturation (i.e. equivalent to one unit weight of .tbd.Si--H), regardless of what other reactive or potentially reactive substitutents may be present. Thus, an equivalent weight of ethylene is its molecular weight. 
     The preferred hydrosilation catalyst is the platinum complex chloroplatinic acid H 2  PtCl 6 .xH 2  O which is commercially available from Aldrich Chemical Company, Inc., Milwaukee, Wis. Other platinum-based catalysts can be employed, however, such as platinum supported on active carbon particles having a diameter of 1-2 mm. The amount of platinum supported on the active carbon can vary from 0.1-5% by weight based on the weight of active carbon. The platinum-on-carbon catalyst can be dried so that it is anhydrous. Other platinum complexes such as platinum acetylacetonate, or chloroplatinic acid complexed with divinyltetramethyldisiloxane and diluted in dimethylvinylsiloxy endblocked polydimethylsiloxane, can also be used. Reference may be had to any of the following U.S. Patents for appropriate hydrosilation catalysts, i.e. U.S. Pat. Nos. 2,823,218, 3,419,359, 3,419,593, 3,445,420, 3,697,473, 3,814,731, 3,890,359, and 4,123,604. 
     The reaction temperature can vary, and optimum temperatures depend upon the concentration of platinum catalyst, and the nature of the reactants. The reaction can be initiated at a temperature below room temperature (0° to -10° C.). The maximum temperature is determined by the stability of the reactants. Ordinarily, it is best to keep the reaction temperature below about 300° C. Best results with most reactants are obtained by carrying out the reaction at about 60° to 180° C. Heat generated by the reaction may raise the temperature up to 200°-250° C. for a short time, however. 
     The optimum reaction time is a variable depending upon the reactants, reaction temperature, and platinum catalyst concentration. Ordinarily, there is no benefit in extending the contact time of the reactants beyond 36 hours, but likewise there is usually no harm, unless an extremely elevated temperature is employed. With many reactants, a practical quantitative yield of product can be obtained in about 3-4 hours. 
     The reaction can be carried out at atmospheric, sub-atmospheric, or super-atmospheric pressure. Here again, the choice of conditions is largely a matter of logic, based upon the nature of the reactants, and the equipment available. Non-volatile reactants are especially adaptable to being heated at atmospheric pressure, with or without a reflux arrangement. Reactants which are gaseous at ordinary temperatures, are preferably reacted at substantially constant volume under autogenous or induced pressure. 
     The hydrosilane or hydrosiloxane for use in the second step hydrosilation can be any silicon hydride with not more than two hydrogen atoms attached to any one silicon atom. 
     It can be a monomer such as HSiR 3 , H 2  SiR 2 , R 2  HSi(OR), or RHSi(OR) 2 . It can also be a polymer or copolymer such as R 2  HSiO(R 2  SiO) a  SiR 2  H, R 3  SiO(R 2  SiO) a  SiR 2  H, R 3  SiO(RHSiO) b  SiR 3 , R 3  SiO(R 2  SiO) a  (RHSiO) b  SiR 3 , or (RHSiO) c . 
     Preferably, R is an alkyl radical such as methyl and ethyl; an aryl radical such as phenyl; or an aralkyl radical such as benzyl. The value for a is zero or any positive number. The value for b is any positive number, and c has a value of 3 or more.

     tetramethylcyclotetrasiloxane (MeHSiO) 4 . 
     Another scenario involves synthesis and characterization of new and unique polymeric silylalkoxysiloxanes with distinctively shaped molecular structures. These silylalkoxysiloxanes are derived from silicates with closely related structures. The silylalkoxysiloxanes have potential as useful reinforcing agents for organosilicon elastomers and composites because of their unique molecular structures. 
     According to this scenario, polymeric silylalkoxysiloxanes derived from polymeric silicates are prepared by treating the silicates with acidic alcohol solutions under controlled conditions. These polymeric silylalkoxysiloxanes are then converted to polymeric alkenylalkoxyalkoxysiloxanes by treating them with alkenyl alcohols. Finally, the polymeric alkenylalkoxyalkoxysiloxanes are converted to polymeric silylalkoxysiloxanes by hydrosilylating them. 
     These polymers were characterized by Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffractomery (XRD).

     Alcohols suitable for use in this embodiment include the various common primary and secondary alkyl alcohols such as methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, pentyl alcohol, and hexyl alcohol, for example; and alkenyl alcohols such as allyl alcohol H 2  C═CHCH 2  OH, 3-buten-1-ol H 2  C═CHCH 2  CH 2  OH, 5-hexen-1-ol H 2  C═CH(CH 2 ) 4  OH, 9-decen-1-ol H 2  C═CH(CH 2 ) 8  OH, and 10-undecen-1-ol H 2  C═CH(CH 2 ) 8  CH 2  OH. Treatment with the alcohols can be conducted separately or in a single step. 
     In Step 1 of the above scenario, at least one mole of HCl for each pendent oxygen is required, but preferably about 5-10 moles is employed. In Step 2 of the above scenario, very low ratios of HCl to polymer can be used, for example 1×10 -3  moles of HCl per mole of polymer. However, it is preferable to use about 5-10 moles of HCl per mole of polymer. Other strong acids can also be used such as hydrobromic acid and hydriodic acid. 
     Solvents useful in carrying out processes according to any of the above Scenarios, are those common in the art. Among the many suitable solvents are for example, acetone, methyl ethyl ketone, cyclohexane, benzene, toluene, xylene, pyridine, picoline, quinoline, and dimethylformamide HCON(CH 3 ) 2 .
