Abstract

After the 4-bromo-3,5-difluorophenyl acrylamide (BDPA) and acrylic acid were introduced into the epoxy acrylate (EA), the photosensitive epoxy acrylate (EFBDPA) with good performance was prepared through chemical graft modification. The structure of EFBDPA was confirmed by FTIR and1H-NMR. When the content of BDPA in EFBDPA was 20%, the cured coating of EFBDPA had better performance than the unmodified EA cured coating, its tensile strength, 80 % decomposition temperatures and the residual carbon ratio were improved 86%, 5.7 °C and 4.2 %, respectively.
