An internal mold release agent comprises a metal salt and an epoxidized vegetable oil and may be prepared by heating a metal salt such as zinc stearate with an epoxidized vegetable oil such as epoxidized soybean oil to obtain a homogeneous clear mixture. The mold release agent can be added directly to a polymeric molding composition and the polymeric system thus formed has the further advantage that it will gel at a significantly faster rate than an untreated system. |
