Abstract

A cyclic olefin extended polyurethane system comprising the reaction product of an isocyanate terminated polyisocyanate with a polyol in the presence of a cyclic olefin extender and, optionally, a liquid ester or other type of extender. Said polyurethane systems are cured, crosslinked, non-spewing, grease compatible, and reenterable. This extended polyurethane is further characterized as having superior insulating properties so that it can be used for repairing, encapsulation or reclaiming electrical or telephone cables as well as hard volume encapsulants for general elastomer use. The extended polyurethane is comprised of a defined polyurethane, novel extender combinations, and optionally, a coupling agent.
