Abstract
In an active hydrogen-containing B-side composition for reaction with a polyisocyanate-containing A-side composition to make a polyurethane or polyurethane/urea elastomer by reaction injected molding, the improvement which comprises a mold release composition which is the reaction product of a C.sub.12 -C.sub.36 fatty acid, a tertiary amine having at least one C.sub.12 -C.sub.18 alkyl substituent and a C.sub.2 -C.sub.21 reactive epoxide.
