Abstract: The present invention relates to radiation curable silicone vinyl ethers and methods for preparing silicone vinyl ethers. More particularly, the present invention relates compositions containing vinyl ether functional silicones and to the preparation and use of silicone vinyl ethers which are curable by addition of photocleavable acids and exposure to ultraviolet or electron beam radiation.

Abstract: The present invention relates to compositions comprising vinyl ether functional siloxanes and aromatic iodonium salt or aromatic sulfonium salt photoinitiators which cure upon exposure to ultraviolet or electron beam radiation. The present invention further relates to use of these compositions in pressure sensitive release applications.

Abstract: The present invention relates to hybrid aqueous silicone-organic composition which are prepared by first forming a silicone oil-in-water emulsion by dispersing an oil phase, containing a silicone polymer and a specific non-ionic surfactant, in a water phase containing a poly(vinyl alcohol) dissolved in water. This silicone emulsion is subsequently mixed with a an aqueous solution of a water-soluble polymer to form the instant compositions which can be applied to substrates to provide coatings having heat resistance comparable to conventional all-silicone systems delivered from organic solvent solution.

Abstract: A curable, reinforced polydiorganosiloxane microemulsion is prepared by adding from 5 to 30 parts by weight of colloidal silica per 100 parts by weight of polydiorganosiloxane in the microemulsion and from 1 to 5 parts by weight of dialkyltindicarboxylate catalyst per 100 parts by weight of the microemulsion to polydiorganosiloxane microemulsion. The curable, reinforced polydiorganosiloxane emulsion can be cast into coherent, elastomeric films of less than 0.4 micrometer thickness.

Abstract: A polydiorganosiloxane emulsion having a combination of high polymer content and low viscosity can be produced by blending a high polymer content polydiorganosiloxane macroemulsion, having a polymer content of greater than 60 percent by weight and an average particle size of greater than 0.14 micrometers, and a high polymer content polydiorganosiloxane microemulsion, having a polymer content of from 20 to 30 percent by weight and an average particle size of less than 0.14 micrometers, with the ratio of the average particle size of the macroemulsion to the average size of the microemulsion of from 5 to 15.
