摘要

A monoester derived from guerbet alcohol and a monocarboxylic acid or a hydroxy carboxylic acid was found to be an effective mold release agent for a thermoplastic molding composition which comprise an aromatic polycarbonate resin. The alcohol of the invention is a guerbet alcohol having about 20 to 60 carbon atoms and the monoacid is characterized in that it has about 1 to 22 carbon atoms.
