Abstract
Maleimide functionalized copolyurethanes were prepared by the reaction of a binary mixture of dibenzyldiisocyanate and 1-(3,5-diisocyanatophenyl)-1H-pyrrole-2,5-dione with a macrodiol (polyethylene-adipate glycol) using diethylene glycol and trimethylolpropane as chain extender and crosslinkers in toluene-dichloromethane solution. Structures of polymers were confirmed by IR and the properties were also studied by thermal and mechanical analysis, and physical methods (contact angle).
