摘要
以 1,2 ,4 -苯三甲酸酐、环氧氯丙烷和光敏剂 1173合成了分子内带有光敏单元的高支化碱溶性聚酯 ,聚合反应转化率在 1h内可达 90 %以上 ;以甲基丙烯酸缩水甘油酯与高支化聚酯反应制得分子内带有光敏单元的高支化碱溶性光固化树脂 ;树脂的热转变温度在 16 0～ 2 10℃ ,在碱水溶液中溶解性好 ,无需外加光敏剂在紫外光照射下便可固化、交联 ,光固化的反差 γ可达到 7.
Highly branched acrylated polyesters containing photoinitiator were synthesized from 1,2,4 trimellitic anhydride, epichlorohydrin and glycidyl methacrylate and photoinititor 1173 . Conversions of monomers to the aqueous soluble polyesters were over 90% within one hour. The acrylated polyesters were obtained by the reaction of aqueous soluble polyesters with glycidyl methacrylate. These resins were aqueous soluble, showed thermal transition at 160~210 ℃, and could be photocured by UV irradiation without additional photoinitiators. Photocuring of these resins were studied with sensitivity E 0 40~160 mJ/cm 2, and contract value γ 1.4 ~7.
