摘要
结构精确的含氟嵌段共聚物具有优异而独特的化学和物理性能,有广阔的应用前景,因此受到广泛的关注。含氟嵌段共聚物可分为两类,一类是侧基含氟嵌段共聚物,另一类是主链含氟嵌段共聚物。活性聚合为嵌段共聚物的合成提供了最为重要的方法,利用它可以合成结构精确、分子量可控、分子量分布窄的嵌段共聚物。根据单体的反应特性选择不同的聚合方法,可以得到不同的含氟嵌段共聚物。本文主要综述了近几年利用各种活性聚合方法合成结构精确的含氟嵌段共聚物方面的进展。
Well-defined fluorinated block copolymers have received much attention recently because they exhibit excellent and unique chemical and physical properties, and various promising applications are expected. Fluorinated block copolymers can be classified into two types, one is side chain fluorinated block copolymers and the other is main chain fluorinated block copolymers. Living polymerization is an important method to synthesize block copolymers with well-defined structure, controlled molecular weight and narrow molecular weight distribution. Different fluorinated block copolymers can be synthesized by different living polymerization processes according to the monomers. This article mainly reviews the recent progresses in the synthesis of well-defined fluorinated copolymers.
