SYNTHESIS OF STARBURST HYPERBRANCHEDPOLYESTERS AND THEIR PHOTOCURING

doi:10.7517/j.issn.1674-0475.1997.02.165

Abstract

Abstract: The divergent synthesis of a series of polydisperse hyperbranched polyesters based upon pentaerythritol and 1,2,4 benzenetricarboxylic anhydride, modified by glycidyl methacrylate and methacrylic anhydride, are described, proceeding in a stepwise growth manner starting from an “initiator core”, building starburst branched arms. The photocuring characteristics of these hyperbranched polyesters and thermal mechanical properties of the UV cured films, such as glass transition temperatures and pendulum hardness etc., have been studied.

Key words: starburst polymer, hyperbranched polysters, photocuring, coating
