Title:
ORGANOPOLYSILOXANE GRAFT POLYMER
Document Type and Number:
WIPO Patent Application WO/2014/125687
Kind Code:
A1
Abstract:
The present invention relates to an organopolysiloxane graft polymer which has an organopolysiloxane segment as the main chain and a copolymer segment derived from an unsaturated monomer as a side chain, wherein the copolymer segment contains a repeating unit derived from an unsaturated monomer comprising a carboxylic acid or a salt thereof, and wherein the content of the organopolysiloxane segment is 35 to 59 mass%, the content of the repeating unit derived from an unsaturated monomer comprising a carboxylic acid or a salt thereof is 4 to 17 mass% and the content of a repeating unit derived from an unsaturated monomer (excluding an unsaturated monomer comprising a carboxylic acid or a salt thereof) having such a property that a homopolymer formed therefrom has a glass transition temperature of 150˚C or higher is 14 mass% or less in the organopolysiloxane graft polymer, and the organopolysiloxane segment has a number average molecular weight of 8000 to 200000 inclusive.
