Flame retardant thermoplastic resin composition

Flame retardant thermoplastic resin compositions containing (A) a rubber-reinforced resin produced by graft-polymerizing a monomer component containing an aromatic vinyl compound and a vinyl cyanide compound as main ingredients in the presence of a rubber polymer particles and (B) 90 to 60 parts by weight of an aromatic polycarbonate. Optionally (C) a phosphate compound and (D) a component containing poly-tetrafluoroethylene and a lubricant may be present.

The present invention relates to a flame-retardant thermoplastic resin composition comprising the following components (A) to (D):

A rubber-reinforced styrene resin composition consisting essentially of:

Rubber-reinforced styrene resin composition and process for producing

A thermoplastic resin composition comprising (A) 75 to 99.8% by weight of a rubber-modified styrene thermoplastic resin, (B) 0.1 to 15% by weight of an aromatic polyester having an intrinsic viscosity in the range of 0.2 to 1.5 dl/g, and (C) 0.1 to 10% by weight of an aromatic polycarbonate. The resin composition provides a painted surface with a superior appearance when a paint is applied on its surface, while maintaining its good fluidity, high impact resistance, and excellent molding heat stability. It can be applied with particular advantage to bodies or chassis of automobiles and the like onto which a paint is coated.

Thermoplastic resin composition

A heat-resistant copolymer obtained by copolymerizing (A) 72-82 parts by weight of .alpha.-methylstyrene and (B) 26-18 parts by weight of acrylonitrile, characterized in that the copolymer contains (a) 0-15% by weight of monomer chain 13 (A)-(A)-(A)--, (b) 50% by weight or more of monomer chain --(A)-(A)-(B)--, and (c) 50% by weight or less of monomer chain --(B)-(A)-(B)--, the total of (a), (b) and (c) being 100% by weight. This copolymer is excellent in heat stability and moldability when molded at high temperatures, and the blending of this copolymer with other thermoplastic resins gives thermoplastic resins with excellent heat resistance.
