摘要
介绍了烷基锂负离子聚合工艺存在的主要弊端,同时指出适当降低高反应速率的途径是调控活性种的反应性。阐述了Lew is酸改性烷基锂负离子聚合的研究进展,认为酸根型络合物反应性和选择性的设定是调控活性负离子聚合的关键,是研发新型负离子引发体系的重要内容。
Main drawbacks of conventional alkyl lithium-initiated anionic polymerization were introduced. It was pointed out that the way to reduce high reaction velocity adequately was the requlation of intrinsic activity of reactive species. The research progress in Lewis acid additives modified alkyl lithium-initiated anionic polymerization was expounded,and the setting of reactivity and selectivity for ＂ate＂ complexes was the key for requlating the living anionic polymerization and the important field for researching and developing novel anionic initiator systems.
