Title:
FLAME-RETARDANT RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP3218192
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a flame-retardant resin composition excellent in impact resistance, flame retardancy and pigmentability by using a composition comprising a polycarbonate resin, a composite rubber-based graft copolymer having a specified composition and a specified mean particle diameter and a flame retardant.
SOLUTION: This composition comprises a polycarbonate resin (A), a graft copolymer (B) prepared by grafting a monomer (b3) such as an aromatic alkenyl compound of a (meth)acrylic ester onto a composite rubber composed of a vinyl-polymerizable functional group containing polyorganosiloxane (b1) and an alkyl (meth)acrylate rubber (b2) (the composite rubber ((b1)+(b2) is composed of 20-40wt.% (b1) and 60-80wt.% (b2), the graft component (b3) constitutes 50-80wt.% of the entire graft polymer (B); and the weight-mean particle diameter is 0.10-0.20μm), an aromatic alkenyl compound (C) and a phosphoric ester compound (D).
