    摘要: A method of molding polymeric materials, such as olefin polymers, in a mold which has a release coating of 50-90 parts by weight polyphenylene sulfide, up to 10 parts by weight polytetrafluorethylene and a filler in an amount of 10-50 parts by weight. The release coating can be utilized to form a plurality of articles without reapplication of the coating. The coating may be applied to the mold as a solution of a volatile solvent or in the melted state.
