| 摘 要： | 以α-羟烷基苯酮(HAPK)、甲苯-2,4-二异氰酸酯(TDI)、聚乙二醇600(PEG600)和丙烯酸-β-羟乙酯(HEA)为原料,通过3步反应,合成了一种可聚合大分子光引发剂:HAPK-TDI-PEG600-TDI-HEA(HTPTH).用IR对反应过程进行了监测.通过Photo-DSC研究了HTPTH引发三丙二醇双丙烯酸酯(TPG-DA)光聚合动力学,考察了光强、引发剂浓度对TPGDA光聚合动力学的影响.结果表明,随着引发剂浓度和光强的增大,最大反应速率对应的转化率、单体最终转化率、最大反应速率都增大,达到最大反应速率所需的时间减小.

| Abstract: | Novel macrophotoinitiator(HTPTH) was synthesized via reaction of α-hydroxy alkylphenones(HAPK),toluene-2,4-diisocynate(TDI),polyethylene glycol 600(PEG 600),and hydroxy ethyl acrylate(HEA).The reaction was followed using FTIR spectroscopy and the product was confirmed using FTIR.The kinetics for photopolymerization of tripropylene glycol diacrylate(TPGDA) using HTPTH as photoinitiator was studied by photo-DSC.It showed that HTPTH concentration and light intensity have similar effect on photopolymerization.The increase in HTPTH concentration and light intensity led to the increase in the polymerization rate and the final conversion. |
