以4，4 ′-二羟基二苯甲酮（DHBP）、丙烯酰氯和哌嗪为原料，合成了一种高分子单组分II型光引发剂（PDABPP），其结构经GPC和1H NMR确证。用实时红外光谱法研究了该光引发剂的光聚合动力学。结果表明，PDABPP是一种比二苯甲酮（BP）/三乙胺（TEA）更有效的光引发剂。随着PDABPP浓度、光照强度和胺浓度的增加，聚合速率和最终转化率增加，诱导期缩短。三丙二醇二丙烯酸酯（TPGDA）与PDABPP在不同叔胺引发体系中的光聚合动力学研究表明，PDABPP/TEA组合体系的聚合速率最高。Polym.工程科学，2008.© 2008年塑料工程师协会
A polymeric one-component type II photoinitiator (PDABPP) based on 4,4′-dihydroxybenzophenone (DHBP), acryloyl chloride, and piperazine was synthesized, and its structure was confirmed by GPC and 1H NMR. The photopolymerization kinetics of the photoinitiator was studied by real-time infrared spectroscopy. It indicated that PDABPP was a more effective photoinitiator than that of benzophenone (BP)/triethylamine (TEA). The rate of polymerization and final conversion increased, and the induction period shortened with increase of PDABPP concentration, light intensity, and amine concentration. The kinetics of photopolymerization for tripropylene glycol diacrylate (TPGDA) incorporating PDABPP in the presence of different tertiary amines as the initiating system indicated that the PDABPP/TEA combination exhibited the highest polymerization rates among the PDABPP/amines combinations.
