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/2019/103092
Kind Code:
A1
Abstract:
Provided is a rubber-containing graft polymer capable of reducing wet heat aging of a molded article while enhancing strength developing properties of a thermoplastic resin. In this rubber-containing graft polymer, the content ratio of a component having a weight-average molecular weight of 800,000 or greater in an organic-solvent-soluble part (100% by mass) of the rubber-containing graft polymer is at least 1% by mass, and the phosphorus content in the rubber-containing graft polymer is 3-30 mmol/kg.
