Title:
INTERPENETRATING NETWORK POLYMER COMPRISING CROSSLINKED ORGANOPOLYSILOXANE AND (METH)ACRYLIC POLYMER, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/145178
Kind Code:
A1
Abstract:
An interpenetrating network polymer characterized by comprising (A) 90-30 mass parts of a crosslinked organopolysiloxane and (B) 10-70 mass parts of a (meth)acrylic polymer (where the total of components (A) and (B) is 100 mass parts) and having a tensile product (product of the tensile strength (MPa) and tensile elongation at break (%)) of a filler-free 2-mm thick sheet measured in accordance with ISO 37 (JIS K-6251) of 1,000 or higher has both the high tensile elongation at break of organopolysiloxane and the high tensile strength of acrylic resin.
