Title:

RUBBERY POLYMER, GRAFT COPOLYMER AND THERMOPLASTIC RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2018/135481

Kind Code:

A1

Abstract:

Provided are: a thermoplastic resin composition which exhibits good moldability and excellent impact resistance, low-temperature impact resistance, weather resistance and appearance of a molded article due to a graft copolymer that uses a rubbery polymer having a high gel content; and a molded article of this thermoplastic resin composition. A rubbery polymer (A) which is a polymerization reaction product of a starting material mixture that contains an alkyl (meth)acrylate, a crosslinking agent (1) represented by formula (1) and a hydrophobic substance so that the content of the hydrophobic substance relative to 100 parts by mass of the total of the alkyl (meth)acrylate and the crosslinking agent (1) is 0.1-10 parts by mass, and which has a gel content of 80-100%. A graft copolymer which uses this rubbery polymer; and a thermoplastic resin composition. CH2=CR1-CO-(X)-COCR1=CH2 (1) In the formula, X represents a diol residue selected from among a polyalkylene glycol residue, a polyester diol residue and a polycarbonate diol residue; and R1 represents H or CH3.
