PURPOSE:To obtain a composition having excellent chemical resistance, impact resistance and moldability and suitable for electronic and electric components, etc., by blending a rubber modified styrene based graft copolymer with an aromatic polyester, etc., at a specific amount. CONSTITUTION:The aimed composition obtained by blending (A) 50-90wt.% rubber modified styrene based graft copolymer having 70-200% graft ratio with (B) 5-50wt.% aromatic polyester and (C) 0-15wt.% aromatic polycarbonate or by blending (A) 45-90wt.% rubber modified styrene based graft copolymer having 40-150% graft ratio with (B) 9-54% aromatic polyester, (C) 0-20% aromatic polycarbonate and (D) 0.5-20wt.% graft copolymer obtained by subjecting a copolymer consisting essentially of olefin unit and functional group-containing unsaturated compound unit to graft polymerization with an aromatic vinyl compound-containing monomer. |
