摘要
A novel fluorine-containing acrylic resin, 4-trifluoromethylphenyl glycerol dimethacrylate (TPGD), was synthesized and the structure was characterized by FTIR, C-13 NMR,H-1 NMR, and F-19 NMR spectroscopy. The conversion of cure reaction, thermal stability, glass transition temperature (T-g), and electrical properties of the TPGD acrylic resin cured with UV radiation were investigated. The thermal stability and T-g of the UV-cured specimens show a maximum value at 1 wt% photoinitiator, due to the formation of advanced network structures. The cured specimens had a relatively low dielectric constant, attributed to the decreased deformation polarizability of segment motion in the fluorine-containing resin.
