摘要：
Polyurethane-modified epoxy monoacrylates (PMEMA) containing two different UV-curable groups (double bond and epoxy groups) were synthesized. The changes of NCO groups during the synthesis process of PMEMA were measured by chemical titration method, and its Fourier Transform Infrared (FTIR) spectra were investigated. The results indicated that polyurethane chain segments can be grafted onto the epoxy monacrylates (EMA) by the reaction of NCO and OH groups. The FUR of PMEMA showed that it contains both double bond of acrylic ester (UV radical curable) and epoxy groups (UV cationic curable).
