ABSTRACT:
An elastomer is molded by a reaction injection molding of polyurethane resins, polyurea resins, polyurethane/urea resins and polyurea/amide resins in the presence of an internal release agent which is a polyester condensate of a saturated or unsaturated fatty acid having a hydroxy group produced by transesterification or a molecular end-aminated or iminated polyester condensate. The elastomer has a good releasing property and a good coating property.
