Abstract

Abstract PURPOSE:To prepare the titled composition having improved fluidity in molding and impact strength of the molded article without lowering the impact strength at the weld line, by compounding a polyethylene and an acrylic rubber to a polycarbonate. CONSTITUTION:86-99wt% (preferably 91-98wt%) polycarbonate is compounded with 0.5-7wt% (preferably 2-5wt%) polyethylene and 0.5-7wt% (preferably 1-5wt%) acrylic rubber. The polycarbonate is the one having a molecular weight of 10,000-100,000, preferably 20,000-50,000. The polyethylene has a molecular weight distribution (MW/Mn) of 5-45, preferably 15-35, and an intrinsic viscosity of 1.5-5dl/g, preferably 2-4.5dl/g measured in decalin at 135 deg.C.
