Abstract
Provided are a vinyl-modified organopolysiloxane useful as a raw material for radical polymerization reactions, especially for biodegradable polymers or copolymers, as well as a method for producing the same. A radical polymerizable polymer or radical polymerizable copolymer in which the vinyl-modified organopolysiloxane is at least a portion of the starting raw material, as well as uses thereof and a method of production, are also provided. A vinyl-modified organopolysiloxane having two or more vinyl-modified groups (RAc) expressed by —R1—C(═O)—O—CH═CHR2 here R1 is a divalent organic group having 4 to 20 carbon atoms, R2 is a hydrogen atom or a methyl group) bonded to a silicon atom in the molecule and having a polyorganosiloxane structure; a radical polymerizable polymer or radical polymerizable copolymer, especially silicone elastomer particles made therefrom; and use thereof.
