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。
The main disadvantages of the alkyllithium anion polymerization process are introduced. At the same time, it is pointed out that the proper way to reduce the high reaction rate is to regulate the reactivity of the active species. The research progress of Lew is acid modified alkyl lithium anion polymerization is considered. It is considered that the setting of reactivity and selectivity of acid radical complex is the key to the regulation of active anion polymerization. It is an important content to develop new anion initiation system.
