A process for preparing molded polymeric products including reacting a polyisocyanate with an active hydrogen-containing composition having internal mold release components. In the process, the active hydrogen-containing composition contains (a) a primary or secondary amine, (b) a metal salt of an organic material having a carboxylic acid group and a siloxane chain wherein, said metal is selected from Groups I-B, II-B, IV-B, V-B, VI-B, VII-B or VIII, and optionally (c) an organic material containing at least one carboxylic acid group, phosphorus-containing acid group or boron-containing acid group wherein said organic material contains a siloxane chain or contains a terminal or pendant aliphatic hydrocarbon chain.
