摘要

The present invention relates to the use of metal organic compounds in a process for providing a moulded plastic article comprising the step of polymerization casting of a curable composition comprising one or more polymerizable molecules or compounds or compositions in the presence of a mould release agent, which in turn comprises a metal organic compound, complexes and/or salts thereof. Such use leads to less surface defects of the moulded article and lower mould damage.
