逐步增长聚合的研究进展

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。

Research Progress on Step-Growth Polymerization

Since step-growth polymerization(SGP) has quite wide application in many fields,and usually the molecular weight of polymers obtained by SGP is gradually increased,more and more importance has been attached to the synthesis of novel polymer materials via SGP.According to the different types of SGP,the research progress of SGP in recent years,especially the polycondensation used in synthesis of polyesters and etc,the polyaddition of diisocyanate monomers and the polyaddition via click reaction are reviewed.In order to further obtain polymers with fine properties,desirable molecular weight and ideal structure by simple preparation method in the future,it is necessary for the SGP research to strengthen the theoretical study,design the monomers with new structure and fully develop the corresponding new synthetic technologies for STG.
