GLOSSY PLASTIC MOLDING AND METHOD OF MOLDING IT

摘要

PURPOSE:To obtain the title molding having fine texture and uniform anisotropic luster and excellent in impact strength by molding a resin composition consisting of a plurality of specified resins under specified conditions. CONSTITUTION:A method of molding a resin composition consisting of 98-50 pts.wt. thermoplastic polyester resin (A) (e.g. polyethylene terephthalate) and 2-50 pts.wt. resin (B) incompatible with the resin A (e.g. PP) to form a molding having the resin B dispersed in the resin A, wherein the resin B in an arbitrary layer in the direction of the thickness of the molding is provided with such a nearly rod-like form as to satisfy the formulas 1<=P/Q<=10 and (P+Q)/L<=0.5 [wherein L is the mean length (mum) of particles of the resin B in the direction of elongation; and P and Q respectively are the mean length and mean width (mum) of the cross section, assumed to be approximately elliptic, of the particles perpendicular to the direction of elongation] and it is oriented in parallel with the outer surface of the molding and in the direction of the flow of the resin composition when molded.
