WIPO Patent Application WO/1996/037555

Kind Code:

A1

Abstract:

A flame-retardant resin composition which comprises 100 parts (by weight, the same applies hereinafter) of a resin comprising (A) a polycarbonate resin having a viscosity-average molecular weight of 16000 to 29000 and (B) a polyalkylene terephthalate resin at a weight ratio of 75/25 to 90/10, (C) 1 to 10 parts of a copolymer comprising a rubbery polymer and at least one monomer selected from the group consisting of aromatic vinyl monomers, vinyl cyanate monomers, acrylic acid, acrylic esters, methacrylic acid, methacrylic esters and maleimide monomers, (D) 2 to 10 parts of an organophosphorus flame retardant, (E) 0.05 to 2 parts of a fluororesin and (F) 0.01 to 10 parts of a halogen-free epoxy compound. The composition does not contain any halogen atom, exhibits excellent flame retardance, impact resistance, heat resistance, moldability, chemical resistance and heat discoloration resistance at a well-balanced state and is suppressed in the problem of silver streaking.
