Document Type and Number:
WIPO Patent Application WO/2022/131365
Kind Code:
A1
Abstract:
A graft copolymer according to the present invention contains: crosslinked (meth)acrylic polymer particles (a) that have an average particle size of 150 nm or smaller and a glass transition temperature of -10°C or lower; and a non-crosslinked methacrylic polymer component (b) that has a weight average molecular weight of 250,000 or higher. At least a part of the non-crosslinked polymer component (b) is grafted to the crosslinked polymer particles (a), and the crosslinked polymer particles (a) constitute at least 1 wt% but less than 50 wt% of the total weight of the crosslinked polymer particles (a) and the non-crosslinked polymer component (b).
