Abstract: A polymer comprising a reaction product of the ingredients including [i] a first homopolymeric or co-polymeric polycarbonate polyol; [ii] an organic polyisocyanate; and [iii] a hydroxy-functional (meth)acrylate having the given formula; and with the proviso that when the first polycarbonate polyol is not co-polymeric, then the ingredients further includes [iv] a second homopolymeric or co-polymeric polycarbonate polyol different from the first one, and wherein the polycarbonate polyol(s) is/are linked to the polyisocyanate via a urethane linkage, and wherein the polyisocyanate is linked to the alkyl moiety of the (meth)acrylate via a urethane linkage.
