【摘要】 通过在有空气和无空气条件下，测定由丙烯酸双环戊烯基酯（CH2=CHCO2-，DCPA）与不同类型光引发剂构成涂膜的光固化时间和分析DCPA及光聚合的不同DCPA聚合物（PDCPA）的红外光谱，提出了DCPA与光引发剂二苯酮（BP）光聚合的一种新反应机理。该机理包括由BP、DCPA的烯丙基氢和氧参予的引发过程，由丙烯酸酯和环戊烯双键参予的链增长过程，以及由高分子自由基和含丙烯酸酯与环戊烯双键的低分子量自由基参予的链终止过程。更多还原

【Abstract】 A new reaction mechanism was proposed for thephotopolymerization of dicyclopentyl acrylate (DCPA) withbenzophenone (BP) as the photo-initiator. The proposal ofthis mechanism is based on the determination of the curingtime of the film of DCPA polymerized with different kindsof photo-initiators and the analysis of the DCPA and DCPApolymers (PDCPA ). This mechanism covers a course ofinitiation participated by the allyl hydrogen and oxygen, achain propagation participated by acrylic ester and thedouble bond of cyclopentene and a chain terminationparticipated by high molecular free radicals and lowmolecular free raidcals containing acrylic ester andcyclopentene double bond.更多还原
