Synthesis of A Novel UV-curable Oligmer 1,4-cyclohexanedimethanol Glycidyl Ether Acrylate and Study on Its UV-curing Properties

摘要

A novel UV-curable oligmer 1,4-cyclohexanedimethanol glycidyl ether acrylate(CHDMGEA) was synthesized by utilizing 1,4-cyclohexanedimethanol glycidyl ether(CHDMGE) and acrylic acid(AA) as starting materials, triphenyl phosphine as catalyst and p-hydroxyanisole as inhibitor. The optimum synthetic conditions were that the concentration of triphenyl phosphine was 0.90% of reactants by weight, the concentration of p-hydroxyanisole was 0.20% of reactants by weight, the reaction temperature was 90-100 ℃, and the molar ratio of CHDMGE to AA was 0.5:1.1. The experimental results show that CHDMGEA is a kind of good UV-curable oligmer. The impact resistance of the UV-cured films with CHDMGEA as oligmer to prepare UV-curing coating was superior to that of the UV-cured films with bisphenol A diglycidyl ether diacrylate(BPGEA) as oligmer to prepare UV-curing coating.
