Polycarbonate-polyol composition and polycarbonate (meth) acrylate compositions and urethane (meth) acrylate compositions prepared therefrom

摘要

A polycarbonate polyol composition which can be used to prepare polycarbonate(meth)acrylate and urethane(meth)acrylate compositions is obtained by the ester interchange reaction of a polycarbonate diol composition with a triol and/or tetraol. The (meth)acrylate compositions have excellent photo and electron beam curability and the cured layers prepared therefrom have excellent heat resistance under moisture conditions.
