摘要： The present invention relates to a process of making a polymerizable hybrid polysiloxane or a polymerizable hybrid siloxane. The process includes reacting an organopolysiloxane or organosiloxane having an average of at least 3 silicon hydride (SiH) groups per molecule, a polyoxyethylene, and a catalyst. The process also optionally includes adding a stabilizer, a catalytic inhibitor, a solvent, and an unsaturated reactant selected from substituted and unsubstituted unsaturated organic compounds.

摘要： Provided in various embodiments are high viscosity, shear-thinning silicone compositions that can be pattern coated directly onto a substrate. The silicone compositions may be prepared by mixing at least one organopolysiloxane, at least one SiH-containing organopolysiloxane, at least one emulsifying agent, a hydrosilyation catalyst and water. The silicone compositions may be applied on a substrate for use in medical devices or wound dressings.

摘要： The present invention relates to a method of preparing hydrophilic silicone gel adhesives by curing a silicone composition. The method includes forming the silicone composition by reacting a polyoxyethylene-organopolysiloxane copolymer having an average of at least 1 functional groups selected from, unsaturated hydrocarbon, hydroxyl, silanol, or combinations thereof and a polyoxyethylene-organopolysiloxane copolymer as cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule in the presence of a catalyst. The polyoxyethylene-organopolysiloxane copolymers react via hydrosilylation or coupling reaction.
