【摘要】 本文对分别加入丙烯腈、醋酸乙烯酯和甲基丙烯酸甲脂的苯乙烯—二乙烯苯共聚反应体系进行了动力学研究,并考察了聚合物的溶胀性能以及所合成的离子交换树脂的交换量和强度。结果表明:在苯乙烯—二乙烯苯共聚反应体系中,加入少量的极性单体,改变了苯乙烯与二乙烯苯的相对聚合速率,从而起到了调节共聚物中化学交联点分布的作用。共聚物网络结构的这一变化使其溶胀性能和强度也相应地发生了一定变化。更多还原

【Abstract】 The paper is concerned with the study on the kinetic of the copolymeriza tion of styrene and divinylbenzene affected by polar monomer (or a third monomer, including acrylonitrile, methyl methaacrylate and vinyl acetate) , together with the swelling and mechanical properties of the copolymers.The results of experiments show that the addition of some polar monomer in the copolymerization of styrene and divinylbenzene can adjust relative polymerizing rate and improve the homogeneity of cross -linking structure of the copolymer The related ion exchange resins have superior properties更多还原
