一、引言研究聚乙烯醇的辐射接枝及其接枝产品的结构性能,在理论和实际上都有重大的意义。近年来,有关这方面的研究正开始萌芽。樱田、沙特,夏比洛、盖阿辛特(N.Geasintov)等分别研究了辐射引发聚乙烯酵与苯乙烯、甲基丙烯酸甲酯及丙烯腈等主要烯类单体的接枝反应,以及产品在各种有机溶剂中的溶胀行为。关于接 I. INTRODUCTION Studying the radiation grafting of polyvinyl alcohol and the structural properties of grafted products have great significance both in theory and in practice. In recent years, research in this area is beginning to sprout. Sakurada, Saudi Arabia, Charlotte, N. Geasintov et al. Studied the grafting reaction of the radically-induced polyvinylalcohol with the main ethylenic monomers such as styrene, methylmethacrylate and acrylonitrile, respectively, As well as the swelling behavior of the product in various organic solvents.
