FLAME-RETARDANT RESIN COMPOSITION AND ITS MOLDING

摘要

PROBLEM TO BE SOLVED: To obtain a flame-retardant resin composition that does not use a halogen-based or phosphorus-based flame retardant causing environmental pollution and performance degradation, satisfies a severe flame-retardant level equal to that obtained by using the halogen-based or phosphorus-based flame retardant and yet has excellent impact strength, weld strength, mold deposit resistance and appearance and its molding. SOLUTION: The flame-retardant resin composition is obtained by mixing (A) 100 parts by mass of a polycarbonate resin with (B) 5-40 parts by mass of a rubber-modified styrene/(meth)acrylonitrile-based graft copolymer obtained by polymerizing at least a styrene-based monomer with (meth)acrylonitrile in the presence of rubber and (C) 0.01-3.0 parts by mass of an alkali metal or an alkaline earth metal salt of sulfonic acid of a PPE (polyphenylene ether) oligomer. The molding is obtained by molding the composition. COPYRIGHT: (C)2006,JPO&NCIPI
