摘要: 紫外光固化具有快速反应、室温操作、低能消耗和无溶剂少污染等优点,现正以日益增长的速度应用于涂层和粘合剂等领域。然而,常规的线形光固化齐聚体具有缠结的柔性分子链结构,其粘度随着分子量的增大而快速增加,故其可加工性和应用受到很大的限制。

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
