ISOCYANATE TERMINATED POLYCAPROLACTONE POLYURETHANE PREPOLYMERS.

摘要

Disclosed are improved isocyanate-terminated polycaprolactone polyurethane prepolymers comprising the reaction product of toluene diisocyanate and polyol compositions. Polyurethane elastomers with good physical and dynamic properties can be obtained by reacting the isocyanate-terminated polycaprolactone prepolymers of the invention with an amine chain extender.
