長期熱老化特性に優れた熱可塑性樹脂組成物
Document Type and Number:
Japanese Patent JP4017053
Kind Code:
B2
Abstract:
A thermoplastic resin composition comprising: (I) 10 to 45% by weight of a rubber-modified thermoplastic resin obtainable by graft polymerizing at least one monomer selected from aromatic vinyl compounds, vinyl cyanide compounds and other vinyl monomers copolymerizable therewith in the presence of a rubber-like polymer, the graft ratio of the rubber-modified thermoplastic resin being 10 to 100% and the intrinsic viscosity eta of the methyl ethyl ketone solubles at 30 DEG C being from 0.2 to 0.8 dl/g; (II) 5 to 30% by weight of a thermoplastic resin obtainable by copolymerizing an aromatic vinyl compound monomer, a vinyl cyanide compound monomer and optionally another vinyl monomer copolymerizable therewith, the weight ratio of aromatic vinyl compound/vinyl cyanide compound/other vinyl monomer being 50-90/10-20/0-30, and the intrinsic viscosity eta of the methyl ethyl ketone solubles at 30 DEG C being from 0.3 to 0.6 dl/g; and (III) 50 to 70% by weight of a polycarbonate resin; the total amount of (I), (II) and (III) being 100% by weight, and the content of the vinyl cyanide compound in (I) and (II) constituting 3 to 12% by weight of the composition.
