综述了由聚氧乙烯链段与聚二烯烃、聚异丁烯、聚乙烯基吡啶、聚丙烯腈、聚丙烯酰胺或聚丙烯酸链段组成的各种嵌段共聚物及接枝共聚物的合成方法,并对其各种性能,包括两亲性质、络合碱金属离子性及微观相分离等进行了总结。

Methods for synthesis of various kinds of block copolymers and graft copolymers containing polyoxyethylene and other segments such as polybutadiene, polyisoprene, poly(vinyl pyridine), polyacrylonitrile, polyacrylamide or polyacrylic acid were reviewed. The block copolymers include diblock copolymers, triblock copolymers, and multiblock copolymers, whereas the graft copolymers include graft copolymers with uniform polyoxyethylene side chains and graft copolymers with polyoxyethylene as main chains. The synthetic methods consist of living anionic polymerization, coupling methods, macroinitiator and free radical polymerization for block copolymers and macromer technique for graft copolymers. Properties of the block and the graft copolymers such as emulsifying properties, surface active properties, microphase separation, complexing properties with alkali metal ions, crystallization properties, ionic conductivity etc. were summerized.
