摘　　要：对用于降低可熔性聚四氟乙烯球晶尺寸的方法现状进行了描述和介绍,其方法主要是在可熔性聚四氟乙烯中加入高结晶度的成核剂,无定形含氟聚合物或含无定形嵌段的聚合物即球晶最小化剂。The current methods for reducing spherulite size of perfluoroalkoxy polymer are introduced in this paper. Nucleating agent with high crystallinity,amorphous fluoropolymer or fluorine- containing multi- segment polymer having an amorphous segment named the minimizing agent are often used into perfluoroalkoxy polymer to reduce spherulite size.
