SILOXANE - POLYETHER COPOLYMERS WITH UNSATURATED FUNCTIONALITIES, AND PROCESS FOR MAKING THEM

摘要

This invention discloses hydrophilic additives in polysiloxane gels, elastom ers and coatings, and novel processes for producing them. The process comprises: (a) redistributing into polysiloxane - polyether copolymers an unsaturated s ilane or siloxane, (b) adding to the mixture of reagents a catalytically effective amount of a basic catalyst; and (c) heating the reaction mixture to effect reaction. Novel siloxane structures of unsaturated aliphatic modified polyether siloxa ne copolymers are also taught.
