Abstract

Abstract An impact-resistant composition comprising a blend of (1) an ABS resin prepared by the so-called bulk suspension polymerization, and (2) a polycarbonate resin, and a flame-resistant resin composition which is formed by incorporating into said impactresistance resin composition a halogen compound and antimony trioxide as flame retardant.
