PURPOSE:To provide the resin composition having excellent processability, impact resistance, welding strength and weather resistance, by blending an aromatic polycarbonate resin with an acrylic ester-containing two-step graft elastic polymer in a specific weight ratio. CONSTITUTION:80-98wt% aromatic polycarbonate resin obtained by the reaction of an aromatic dihydroxy compound with a carbonate precursor and 20-2wt% acrylic acid-containing two-step graft elastic copolymer (e.g. HIA-15 manufactured by Kureha Chemical Industry Co. Ltd.) obtained by the two-step graft polymerization of a (me)thacrylate ester as a princifal component with monomers such as styrene, butadiene or acrylonitrile are mixed and milled with an extruder, a Bambury mixer roller to provided the object resin composition. |
