Progress in study on hyperbranched polymer modified epoxy resins

Hyperbranched polymers had been applied in in many fields due to their unique architecture and properties, especially the applications on modification of resins, hyperbranched polymers could be used as toughening agents of thermosetting resins. The performance and the application of epoxy resin and the structural characteristics of hyperbranched polymers were introduced. Aspects of research of hyperbranched polymer modifiedepoxy resin in recent years were focused, such as mechanical properties, curing behavior and thermal properties. Some future directions for the research on hyperbranched polymers as modifiers for epoxy resins were anticipated from the author＇s viewpoint.
