Abstract: A process for preparing a hyperbranched polycarbonate polyol includes reacting a polyfunctional alcohol and an ester or carbonate in the presence of a catalyst and then heating the reaction mixture under azeotropic reflux conditions to form an alcohol or water. The alcohol or water by-product is then removed from the reaction mixture, thereby pushing the reaction forward.

Abstract: The invention relates to aqueous polyurethane dispersions that are curable with UV radiation. The polyurethanes are chain-extended with aromatic, cycloaliphatic or aliphatic diamine compound and cross-linked with aliphatic triamine compound. The polyurethanes are useful dispersions for coating various substrates. The use of the invented dispersions results in high hardness, very good flexibility and good chemical resistance in both clear coats and pigmented coatings before and after UV curing combined with very good adhesion to different substrates.
