摘要： A method of polymerizing an oligomer comprising a polydiorganosiloxane, polydiorganocyclosiloxane, or mixture thereof in the presence of reinforcing filler using a catalytic amount of sulfuric or sulfonic acid is described. The sulfonic acid is of the formula XSO.sub.3 H wherein X is selected from the group consisting of halogen, alkyl, aryl, alkoxy, and alkaryl radicals. The dispersion of reinforcing filler in polydiorganosiloxane is produced using less energy, with fewer manufacturing steps than current commerical processes. The silicone polymer-filler mixture produced by this method is useful as electrical insulation compounds, in greases, and in producing curable compositions useful as sealants, caulking compounds, and heat curable silicone elastomeric compositions.

摘要： An aqueous silicone emulsion is described which provides an elastomeric product upon removal of the water under ambient conditions. The emulsion comprises a continuous water phase and an anionically stabilized dispersed silicone phase which is a graft copolymer of a hydroxyl endblocked polydiorganosiloxane and an alkali metal silicate. The emulsion is formed and maintained in a stable condition by control of the pH within the range of 8.5 to 12 inclusive. In the method of preparing the emulsion, an organic tin compound can be employed to accelerate the formation of the graft copolymer.

摘要： Improvement in impact strength of certain vinylic polymers is obtained by dissolving a mercaptosiloxane-dimethylsiloxane copolymer in a vinylic monomer and converting the monomer to a polymer by bulk or suspension polymerization in the presence of a free radical generator. For example, a copolymer of mercaptopropylmethylsiloxane and dimethylsiloxane is dissolved in styrene and the styrene is copolymerized with acrylonitrile in bulk and/or in water suspension using benzoyl peroxide as a catalyst.

摘要： Glycol co-esters of drying-oil fatty acids and polymerizable unsaturated carboxylic acids are formed by a novel bi-phase catalysis in liquid-liquid or liquid-solid dispersions. The co-esters form directly from drying-oil acids and partial glycol esters of vinylic carboxylic acids, or vice versa. Complete removal of the by-produced water by distillation is unnecessary and the commonly encountered side reactions of direct esterification are suppressed since reaction temperatures can be as low as ambient. The expensive acid chlorides or anhydrides combined with acid acceptors, previously used to prepare such co-esters, are circumvented along with the by-produced hydrochlorides or carboxylates which must be recovered and disposed in an environmentally acceptable way. The co-esters formed here are useful in free radical copolymerizations that provide novel film-forming polymers capable of cross-linig when dried in air. They can be formed in bulk, solution or as latexes. When the carbinol-bearing structure of the co-ester is polymeric, novel polymers are produced having both pendant polymerizable vinyl carboxylate and drying-oil structures that rapidly air-cure at ambient temperature.

The resulting emulsion is maintained at a temperature of 15.degree. to 30.degree. C. for at least 5 hours at a pH of less than 5 until a crosslinked polymer is formed, then this emulsion is admixed with base to a pH of greater than 7. The resulting emulsion is reinforced by adding greater than 1 part by weight of colloidal silica sol or silsesquioxane to yield a latex. Removal of water from the latex results in a reinforced elastomer. This method yields a latex which can be applied and dried immediately after mixing to yield an elastomer.

摘要： This invention is a method of producing a latex of crosslinked polydiorganosiloxane reinforced with colloidal silica. The method allows the production of a latex having a relatively high amount of silica present in relation to the polymer because the water used to form the emulsion can be that present in the acidic colloidal silica sol used in the method. The high solids latex can be useful as a caulking material. The method homogenizes a hydroxyl endblocked polydiorganosiloxane, a silane of the formula R'.sub.a Si(OR.sup.3).sub.4-a where R' is a monovalent hydrocarbon radical of up to 12 carbon atoms, R.sup.3 is an alkyl radical of 1 to 6 carbon atoms, a partial hydrolyzate, or mixture of silane and hydrolyzate, and a is 0 or 1; a surface active anionic catalyst of the formulae R.sup.2 C.sub.6 H.sub.4 SO.sub.3 H wherein R.sup.2 is a monovalent hydrocarbon radical of at least 6 carbon atoms, R.sup.2 OSO.sub.2 OH, or ##STR1## wherein R.sup.4 is H or R.sup.2 ; and greater than 1 part by weight of colloidal silica present as an acidic sol in water. This homogenized mixture is an oil-in-water emulsion. This emulsion is maintained at a temperature of 15.degree. to 30.degree. C. for at least 5 hours at a pH of less than 5 until a crosslinked polymer is formed. The product is a latex which produces an elastomer upon removal of the water at room temperature. Shelf stable products are produced by adjusting the pH to from 7 to 12.5.

摘要： Hydroxyl-endblocked polydiorganosiloxane oligomer is polymerized through the use of a catalyst mixture of quaternary ammonium carboxylate and carboxylic acid. The method heats the mixture of oligomer and catalyst to a temperature in the range of from 90.degree. C. to 150.degree. C., removing water from the mixture, until the desired degree of condensation is achieved. When cooled, the product is a stable polydiorganosiloxane of increased molecular weight. The catalyst can be inactivated by heating and removing volatile byproducts. One embodiment of the method adds an acidic or neutral reinforcing filler to the mixture before polymerization to yield a storage stable silicone polymer-filler mixture which is useful in a manner similar to conventionally produced silicone polymer-filler mixtures.
