Abstract
The invention relates to reaction injection molded elastomers derived from high molecular weight polyether polyols, an aromatic diamine chain extender, a polyisocyanate and a hydroxyl-containing organotin catalyst. The reaction injection molded (RIM) elastomers of this invention are useful, for example, as automobile body parts.
