Flame-retardant resin composition

Abstract

Abstract PURPOSE:A composition showing improved inpact resistance and flame retardance as an orientated thin molded article, obtained by blending a polymer prepared by grafting highly a vinyl monomer to a rubber-like polymer having a specivic particle diameter distribution with a flame-retardant. CONSTITUTION:(A) 100pts.wt. resin composition having 8-35wt% rubber content, comprising a graft polymer having 70-150 graft ratio obtained by polymerizing monomers comprising a monovinyl aromatic monomer, an unsaturated nitrile monomer, and, if necessary, a (meth)acrylic acid ester monomer with rubber-like polymer latex having particle diameter distribution wherein <=15wt% particles having <=1,500Angstrom particle diameter, >=60wt% particles having 1,500-3,500Angstrom particle diameter, and <=25wt% particles having >=3,500Angstrom particle diameter is blended with (B) 5-30pts.wt. a halogenated flame-retardant, and (C) 0-20pts.wt. antimony oxide.
