ABSTRACT:
The invention relates to reaction injection molded elastomers derived from high molecular weight amine terminated polyethers, a chain extender, a polyisocyanate and a high molecular weight organic acid which add green strength and aid mold release. The reaction injection molded (RIM) elastomers of this invention are useful, for example, as automobile body parts.
