ABSTRACT:
New linear polyurethane elastomers have been developed by combining a polycarbonate polyol, a polyether polyol, at least two extenders, and a solid diisocyanate compound. Preferably, the diisocyanate compound is modified by reaction with one of the extenders to form a modified diisocyanate component which is a liquid at room temperature prior to reaction with the polyols and other extender. These new elastomers possess a unique combination of hydrolytic stability, toughness, flexibility, and relatively low temperature processability.
