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 8W35wt% rubber content, comprising a graft polymer having 70W150 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 ≤1,500 particle diameter, ≥60wt% particles having 1,500W3,500 particle diameter, and ≤25wt% particles having ≥3,500 particle diameter is blended with (B) 5W30pts.wt. a halogenated flame-retardant, and (C) 0W20pts.wt. antimony oxide.
