Abstract
Polyester based polycarbonate (meth)acrylates prepared by the reaction of a alkylene or arylene diol polycarbonate with an anhydride or its dicarboxylic acid to form a carboxyl terminated diester, reacting the diester with a diglycidyl ether and an acrylic or methacrylic acid to form an acrylate terminate polymer which is useful for radiation cured coatings which have superior adhesion and reverse impact strength when applied to plastic substrates.
