ゴム強化熱可塑性樹脂組成物及び樹脂成形品
Document Type and Number:
Japanese Patent JP6454272
Kind Code:
B2
Abstract:
A rubber-reinforced thermoplastic resin composition comprising: a graft copolymer (A) forming a dispersion phase and obtained by graft copolymerization, in the presence of a rubber-like polymer (a), of at least one type of monomer (b) selected from a group comprising an aromatic vinyl-based monomer, a vinyl cyanide monomer, a (meth) acrylate ester-based monomer, and other copolymerizable monomers; and a copolymer (B) forming a continuous phase and being a copolymerization of at least one type of monomer (b) selected from a group comprising an aromatic vinyl-based monomer, a vinyl cyanide monomer, a (meth) acrylate ester-based monomer, and other copolymerizable monomers. The rubber-reinforced thermoplastic resin composition is characterized by the viscosity ratio (η1/η2), between the viscosity (η1) at a shear rate of 1 × 101/sec and the viscosity (η2) at a shear rate of 1 × 103/sec, being no more than 10 as measured using a capillary rheometer having a 1 mm φ bore diameter.
