Abstract
Linear polyurethane elastomers of a polyol component, at least two extender components, and a diisocyanate compound are prepared by reacting the diisocyanate compound with one of the extender components to form a modified diisocyanate component having a functionality of about 2 prior to reacting this modified component with the other components of the elastomer. These new elastomers can be processed at lower temperatures compared to elastomers prepared from similar compositions wherein the isocyanate compound is not modified.
