Internal mold release compositions

A process for preparing polymeric products which process comprises mixing and injecting into a suitable mold "A-side" component comprising a polyisocyanate and/or polyisothiocyanate and a "B-side" component comprising a product resulting from aminating a material prepared by reacting an initiator compound having from 2 to about 8 reactive hydrogen atoms with an alkylene oxide, halogen substituted or aromatic substituted alkylene oxide or mixtures thereof, said product having an average molecular weight of from about 200 to about 6000 and containing at least one primary and/or secondary amine group per molecule or a mixture of such materials, and from about 0.5 to about 6 weight percent, based on the weight of the "B-side" component, of a Group I-A or II-A metal salt of a carboxylic acid containing at least one terminal or pendant saturated or unsaturated aliphatic hydrocarbon chain containing at least about 7 carbon atoms, wherein said "B-side" component is devoid further comprises an organic material containing at least one carboxylic acid group, phosphorus-containing acid group or boron-containing acid group or mixture of such materials wherein said organic material contains a siloxane chain or contains at least one terminal or pendant saturated or unsaturated aliphatic hydrocarbon chain containing at least about 7 carbon atoms.
