ABSTRACT:
A process for the preparation of a synthetic resin-shaped article having good antistatic properties is provided, which entails a) polymerizing a monomer mixture containing monomers (A), (B) and (C) to form a first copolymer; b) subsequently polymerizing monomers (D) and (E) in the presence of the first polymer to prepare a second copolymer; forming a film of the second copolymer on the molding surface of a casting mold; and supplying a starting material capable of forming a synthetic resin into the casting mold and polymerizing the starting material to form the substrate in the casting mold, thereby transferring the film of the previous step to the surface of the substrate from the molding surface of the casting mold.
