Title Hyperbranched polymers in cationic photopolymerization of epoxy systems

Abstract Hyperbranched polymers (HBP) belong to a new group of molecules called dendritic polymers, which have peculiar and often unique properties. In this work different HBP were investigated in cationic photopolymerization of epoxy systems. They induced an increase of final epoxy conversion. Moreover a clear increase in toughness was observed and attributed to the plasticization effect induced by the presence of HBP. This effect is particularly interesting for epoxy thermosets, which are characterized by good mechanical properties, but they are brittle and fragile. By increasing the toughness properties of these photocured resins it may be possible to broad their applications.<br /><br />Advances in Photoinitiated Polymerization<br />The 228th ACS National Meeting, in Philadelphia, PA, August 22-26, 2004
