PURPOSE: To provide a combustion-resistant thermoplastic compsn. constituted by compounding a resin selected from an aromatic polycarbonate and the like and a graft copolymer and reduced in the tendency to the formation of a hole at a time of combustion and capable of also satisfying requests of the Canadian Standard Association. n CONSTITUTION: 0.5-20 pts.wt. of a phosphorus compd. represented by formula (wherein R 2 -R 3 are 1-8C alkyl and m and n are 0 or 1) (D), 0.05-5 pts.wt. of fluorinated polyolefin with an average particle size of 0.5-1,000 μm (E) and 1-50 pts.wt. of polyarylene sulfide (F) are compounded with the sum total 100 pts.wt. of 10-95 pts.wt. of a resin selected from an aromatic polycarbonate, an aromatic polyester carbonate or the like (A), 5-70 pts.wt. of a graft polymer (B) consisting of 5-95 pts.wt. of a polymer mixture B 1 of a member selected from styrene and the like and a member selected form (meth)acrylonitrile or the like and 5-95 pts.wt. of granular rubber B 2 with an average particle size of 0.05-5 μm and a gel content of 60% or more and 1-50 pts.wt. of a thermoplastic resin (C) being a copolymer C 1 of a member selected from styrene or the like and a member selected from acrylonitile or the like or polyalkylene phthalate C 2 . n COPYRIGHT: (C)1992,JPO |
