摘要： PROBLEM: The present invention provides 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. Furthermore, the present invention provides 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.
SOLUTION: A vinyl-modified organopolysiloxane having two or more vinyl-modified groups (R Ac ) expressed by -R 1 -C(=O)-O-CH=CHR 2 (where R 1 is a divalent organic group having 4 to 20 carbon atoms, R 2 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.

摘要： PROBLEM
To provide silicone elastomer particles having a crosslinked structure which is active with respect to biodegradability, and can provide texture and feel during use that is equal to or higher than conventional silicone elastomer particles when blended in a cosmetic composition or the like, a reactive group-containing polycaprolactone compound having a specific structure and useful as a raw material for synthesis reactions, and a method for producing the same.
SOLUTION
A polycaprolactone compound containing a reactive group having two or more modified polycaprolactone structures having the following structural formula (1): {in the formula, n is a number in the range 1 to 5 and Ra is a specific (meth)acryl terminal group or alkenyl terminal group} (specifically, a compound selected from the aforementioned (meth)acryl-modified polycaprolactone compounds and alkenyl-modified polycaprolactone compounds) and their use as raw materials for silicone elastomer particles.
