Abstract
Mold release agents useful for the production of plastic molded parts having reduced concentration of undesirable, potentially health hazardous substances in the edge zone and on the surface of the molded part and a process for the production of low toxicity plastic molded parts using such mold release agents. These mold release agents have at least one group which is reactive with the undesirable materials that form on the surfaces and in the edge zones of the molded parts.
Claims3
