Plastic molding having luster and method of molding the same.

摘要

A plastic molding produced by molding a resin composition comprising 98 to 50 parts by weight of a thermoplastic polyester resin (A) and 2 to 50 parts by weight of a resin (B) incompatible with the thermoplastic polyester resin (A), the resin (B) being dispersed in the resin (A), wherein the resin (B) has in an arbitrary layer in the direction of the thickness of the plastic molding a substantially rodlike form satisfying the requirement represented by the following formulae (1) and (2) and is oriented in parallel to the outer surface of the plastic molding and in the direction of flow of the resin composition in molding: 1 (P + Q)/L wherein L, P and Q represent the size of the particle of said resin (B) and respectively have the following values: L: the average length ( mu m) in the direction of stretching of the particle; P: the average major axis ( mu m) in the case where a section perpendicular to the direction of stretching of the particle is approximated to be elliptical; and Q: the average minor axis ( mu m) in the case where the section perpendicular to the direction of stretching of the particle is approximated to be elliptical.
