ABSTRACT:
The invention relates to reaction injection molded elastomers containing a major amount of polyurea linkages derived from high molecular weight amine terminated polyethers, an aromatic diamine chain extender and a polyisocyanate. The reaction injection molded (RIM) elastomers of this invention are useful, for example, as automobile body parts.
