ABSTRACT:
A crosslinkable polyurethane or polyurethane/polyurea comprises the reaction product of a composition comprising a macrodiol or macrodiamine, 2-gl;yceryl acrylate or 2-glyceryl methacrylate, a diisocyanate, and optionally a small glycol or small diamine as chain extender. The performance properties of the polyurethanes and polyurethane/polyureas can be controlled by adjustment of the crosslink level and/or curing parameters.
