Synthetic resin molded article having excellent antistatic property and process for preparing same.

摘要

A synthetic resin molded article having a good antistatic property is disclosed, which is composed of a body of a synthetic resin (B) having a surface layer which is predominantly comprised of an antistatic polymer (A) and is integral with the body (B). The antistatic polymer (A) mainly composed of units of a quaternary ammonium base monomer of the formula: wherein R1 is H or methyl, R2 through R4 are H, unsubstituted or substituted (Cl - 9) alkyl, m is 1 - 10 and X<-> is an anion of a quaternizing agent. The molded article is made by forming a film of the antistatic polymer (A) on the molding surface of a casting mold, casting a polymerizable material to be formed into the synthetic resin (B) as the base material in the casting mold, and polymerizing the polymerizable material to form a body of the synthetic resin (B), simultaneously rendering the film of the polymer (A) integral with the body of the base material.
