【摘要】 <正> 近年来,人们对光聚合反应包括光引发聚合、光交联、光固化等发生很大的兴趣。一个重要的原因是它具有广泛而重要的实用价值。光聚合体系的研究,作为一系列重要工业部门——涂料工业、印刷业(制版和光敏油墨)、电子精细加工业(光致抗蚀剂)以及其他如影象技术等的基础,受到人们的重视。在光照下快速形成交联的立体网状结构的光聚合反应,更引起一些部更多还原

【Abstract】 By using laser cloudiness apparatus, the initiating effectiveness of photointtiator in the reaction of photocuring was studied in the system of benzoin ether and benzophenone. In pentaerythrite acrylate with dichloroethane-isopropyl alcohol as solvents, it is found that the order of the initiating effectiveness of benzoin ethers is as follows: dimethylether>diethyl ether>isopropyl ether>methyl ether>ether. The structure of the apparatus and the experiment procedure are also introduced.更多还原
