Reaction injection molded elastomers made using high molecular weight amine terminated polyethers and small amounts of low molecular weight amine terminated polyethers

The invention relates to reaction injection molded elastomers derived from high molecular weight amine terminated polyethers having greater than 50 percent of their active hydrogens in the form of amine hydrogens, low molecular weight amine terminated polyethers and a polyisocyanate. The reaction in...

Zusammenfassung:The invention relates to reaction injection molded elastomers derived from high molecular weight amine terminated polyethers having greater than 50 percent of their active hydrogens in the form of amine hydrogens, low molecular weight amine terminated polyethers and a polyisocyanate. The reaction injection molded (RIM) elastomers of this invention are useful, for example, as automobile body parts.
