摘要:
The present invention is concerned with a process for molding thermoplastic, high molecular weight aromatic polycarbonates the improvement which comprises adding to the aromatic polycarbonate from about 0.001 to 1% by weight of a mold release agent selected from the group consisting of perfluoroalkanesulphonic acid amides, cyclimmonium salts of perfluoroalkanesulphonic acids and ammonium salts of perfluoroalkanesulphonic acids.
