Patent ID: 7244786

Claim:
A flame-retardant resin composition consisting essentially of: (A) 100 parts by weight of a rubber-reinforced polystyrene resin, (B) from 0.1 to 20 parts by weight of an epoxy-modified phenolic resin of the following general formula (1), and (C) from 1 to 30 parts by weight of an aromatic phosphate of the following general formula (2): wherein R 1 represents a hydrogen atom, or an alkyl group having from 1 to 5 carbon atoms, n represents an integer of at least 3 and the compound may be a mixture with different integer of n: wherein Ar 1 , Ar 2 , Ar 3 and Ar 4 are the same or different, and each represents a phenol group, or a phenol group substituted by an organic residue containing no halogen; n indicates an integer of 0 or more, and the compound may be a mixture with different integers of n; k and m each indicate an integer of from 0 to 2, and (k+m) is an integer of from 0 to 2; X represents any of the following: in which R 2 to R 9 are the same or different, and each represents a hydrogen atom, or an alkyl group having from 1 to 5 carbon atoms; Y represents a direct bond, or O, S. SO 2 , C(CH 3 ) 2 , CH 2 or CHPh; Ph represents a phenol group, and from 1 to 100 parts by weight of the polyester resin (D), relative to 100 parts by weight of the rubber-reinforced polystyrene resin (A), wherein the polyester resin (D) is a polyethylene terephthalate resin and/or a copolymer which contains polyethylene terephthalate units.
