近十年来,苯乙烯之輻射聚合研究頗受人注意,因輻射聚合方法不仅有实用之可能性,而且苯乙烯也是輻射引发聚合反应历程的一个良好的研究对象。虽然在文献中有关苯乙烯的輻射引发聚合的报导巳不少,但关于动力学方面的研究結果彼此間尚存在着若干差异。本文描写了苯乙烯在Co~(60)Υ輻射輻照下,不同剂量率对聚合速率、聚合物平均聚合度,以及对聚合产率G值等三方面的影响。 In the recent ten years, the research of radiation polymerization of styrene has drawn much attention. The radiation polymerization method not only has the practical possibility, but also styrene is a good research object of radiation-induced polymerization process. Although there have been many reports on radiation-induced polymerization of styrene in the literature, there are still some differences between the kinetic studies. This paper describes the effects of different dose rates on the polymerization rate, the average degree of polymerization of polymers, and the G value of the polymerization yield under the irradiation of Co ~ (60) Y.
