Abstract

New UV-thermal dual hybrid curable organosilicon-modified epoxy monoacrylates (OMEMA) were synthesized in this study. The changes of NCO groups during the synthesis process of OMEMA were measured by chemical titration method, and its Fourier Transform Infrared (FTIR) spectra were investigated. The results indicate that organosilicon chain segments can be grafted onto the epoxy monacrylates (EMA) by the reaction of NCO and OH groups. The FTIR of OMEMA show that it contains both double bond of acrylic ester (UV curable) and epoxy groups (thermal curable).
