Abstract

This paper reviews synthesis and property of UV-curing materials based on hyperbranched polymers, calixarenes, and noria. The synthesis of UV-curing hyperbranched polymers was examined by the polyaddition of bisepoxide as A2- type monomer, triscarboxilic acid as B3-type monomer, and methacrylic acid as C-type monomer, i.e., A2＋B3＋C method afforded corresponding hyperbranched polyesters with methacryloyl groups at the ends. The synthesized hyperbranched polyester had good solubility, good film-forming property, and high UV-curing reactivity. Furthermore, the obtained cured films of hyperbranched polymers had higher cross-linking densities compared to those of linear polymer. Next, calixarene derivatives and noria derivatives with pendant radical polymerizable groups and cationic polymerizable groups were synthesized, and their physical properties and UV-curing reactivity were examined. As the result, synthesized calixarene derivatives and noria derivatives had also good solubility and good film-forming property. Especially, their UV-curing reactivity were superior to those of linear polymers and hyperbranched polymers.
