Synthesis, photopolymerization kinetics and thermal properties of UV-curable witerborne hyperbranched polyurethane acrylate dispersions

摘要

Of the waterborne UV curable systems available, the polyurethane acrylates have probably been most widely used, due to their superior performance properties (abrasion resistance, impact and tensile strength). There have been few studies of the polymerisation kinetics of these systems containing hyperbranched groups. This article describes the preparation and the properties of UV curable waterborne hyperbranched polyurethane acrylate dispersions (WHBPUADs).
