摘要： Adding styrene and acrylonitrile and/or methylmethacrylate to an aqueous emulsifier system comprising a redox polymerization catalyst and an emulsified polyorganosiloxane having a molecular weight of at least 10,000 and an average particle size of 1000 to 10,000 Angstroms, continuing the polymerization until substantially all the monomers have polymerized, coagulating a styrenic copolymer compositiion, separating the styrenic copolymer composition from the aqueous medium and recovering the styrenic copolymer composition provides a composition consisting of a continuous styrenic copolymer matrix having dispersed therein gelled particles which are essentially free of inclusions of free styrenic copolymer, and present in an amount sufficient to provide a polyorganosiloxane gel ratio of at least 0.65. The composition is a thermoplastic which has a notched Izod impact strength of greater than 1.0 foot pound per inch of notch, which has improved lubricity and weatherability.

摘要： A controlled release coating composition comprising an organic solvent solution of an organopolysiloxane and a solvent soluble polymer of a polymerizable unsaturated aliphatic dibasic acid or derivative thereof. Incremental changes in the proportion of said solvent soluble polymer lead to incremental changes in the release force of the coatings produced with such compositions. Processes for applying the new coating compositions are also described. A typical composition comprises a toluene solution of a polymethylsiloxane and a C18 alkyl vinyl ether/maleic anhydride copolymer in a 10:1 ratio on a weight basis.
