Title:
RUBBER-CONTAINING GRAFT POLYMER, RESIN COMPOSITION CONTAINING RUBBER-CONTAINING GRAFT POLYMER, AND MOLDED ARTICLE OF SAME
Document Type and Number:
WIPO Patent Application WO/2019/069976
Kind Code:
A1
Abstract:
Provided is a rubber-containing graft polymer that can be uniformly dispersed in a thermoplastic resin including an alloy in a particle diameter of 100-300 nm, and whereby strength development properties needed in a rubber-containing graft polymer can be enhanced. In this rubber-containing graft polymer (A), the particle diameter of rubber to be grafted is 100-300 nm, the content ratio of organic-solvent-insoluble components in the rubber-containing graft polymer (100 mass%) is 92-99.5 mass%, and the weight-average molecular weight of organic-solvent-soluble components of the rubber-containing graft polymer is 250,000-700,000.
