逐步增长聚合应用面广,且聚合物分子量是逐步增加的,近来利用逐步增长聚合可以合成新型高分子材料日益引人注目。按照逐步增长聚合的不同类型,对近年来逐步增长聚合研究的新进展,特别是对合成聚酯等的缩聚反应,以及利用二异氰酸酯和Click反应的逐步加成聚合等进行了综述。为了进一步获得性能优良、分子量可控、结构理想且制备方法简便的高分子材料,加强逐步增长聚合理论研究、开发新型结构的单体,并充分开发相应的聚合新技术,是今后逐步增长聚合研究的重点。
Gradual growth polymerization is widely used, and the molecular weight of the polymer is gradually increased. Recently, it has become increasingly attractive to synthesize new types of polymer materials by using gradual growth polymerization. In accordance with the different types of gradual increase polymerization, the recent progress in the research of gradual increase polymerization, especially the polycondensation reaction of synthetic polyesters and the stepwise addition polymerization using diisocyanate and Click reaction, are reviewed. In order to further obtain polymer materials with excellent performance, controllable molecular weight, ideal structure and simple preparation method, it is necessary to enhance the theory of gradual increase polymerization, develop monomers of new structure and fully develop new polymerization technologies, the key of.
