发明名称 THERMOPLASTIC RESIN COMPOSITION EXCELLENT IN WELDABILITY AND WELDED MOLDING
摘要 PROBLEM TO BE SOLVED: To obtain a composition excellent in weldability by mixing a thermoplastic aromatic polycarbonate resin with a thermoplastic polyester resin, a methacrylic acid ester resin and a copolymer of an alkyl acrylate with an alkyl methacrylate in a specified ratio. SOLUTION: This composition comprises 5-90 wt.% thermoplastic aromatic polycarbonate derived from an aromatic dihydroxy compound such as bisphenol A, 90-5 wt.% thermoplastic polyester resin having an intrinsic viscosity of 0.4 or above and 1-10 wt.% methacrylic acid ester resin and 1-10 wt.% copolymer of an alkyl acrylate with an alkyl methacrylate. The methacrylic acid ester resin is prepared by graft-polymerizing 50-90 pts.wt. monomer mixture containing 60-100 wt.% alkyl methacrylate in the presence of an emulsion containing 10-50 pts.wt. crosslinked acrylic acid ester elastomer.
