Abstract:

This paper reviewed the research progress in the modification of epoxy resin with hyperbranched polyesters (HBPEs). The synthetic methods of hydroxyl-terminated/carboxyl-terminated/epoxy-terminated/amino-terminated HBPEs were summarized at first. The research progress in the impact modification of epoxy resins by the HBPEs with different end groups and their toughening mechanism was introduced. The influence of the HBPEs with different end groups on the curing properties of epoxy resin was also discussed. In addition, the problems in the modification of epoxy resins with HBPEs were analyzed. The research directions in future will focus on the green synthetic methods of HBPEs with a low cost as well as the multifunctionalization of HBPEs.

Key words: hyperbranched polyester, epoxy resin, toughing modification, curing modification
