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...
