VEHICLE-EXTERIOR MOLDED MEMBER WHICH IS SUITABLE FOR GALVANIZING AND PAINTING AND USABLE WITHOUT PAINTING NOR GALVANIZING

摘要

PROBLEM TO BE SOLVED: To provide a vehicle-exterior molded member which is suitable for galvanizing and painting, usable without painting nor galvanizing and adaptable to various cases such as partial galvanizing, co-use of galvanizing and painting or the like. SOLUTION: This member is obtained by molding a resin composition obtained by blending (D) 0.01-5.0 pts.wt of a polysiloxane with a 100 pts.wt. (A)+(B)+(C)=100 pts.wt.} of a composition comprising (A) 10-80 pts.wt. of a graft polymer of a graft ratio of 10-50% obtained by polymerizing an aromatic vinyl and vinyl cyanide with an ethylene/propylene rubber, (B) 10-60 pts.wt. of a graft polymer of a graft ratio of 50-80% obtained by polymerizing an aromatic vinyl and vinyl cyanide with an acrylic ester rubber of a weight average particle size of 0.05-0.3μm and (C) 10-80 pts.wt. of a copolymer having a specific viscosity of 0.5-0.8 obtained by polymerizing 50-74 wt.% of an aromatic vinyl monomer and 26-50 wt.% of vinyl cyanide.
