Poly(propylene oxide) containing two acrylate end groups was prepared firstly by reaction of poly(propylene oxide) with tolylene diisocyanate and 2hydroxyethylene acrylate. Then it was used as a reactive modifier for epoxy resins of diglycidyl ether of bisphenol A type in the presence of curing agent containing amine groups. Due to the linkage between acrylate end groups and curing agents, the compatibility of epoxy resin with modifiers was improved.
