摘　　要：在含嵌段共聚物可结晶型“稀固体溶液”的结晶过程中,我们已发现共聚物胶束既可起着成核剂的作用,也可起抑制成核数目的作用.本文根据进一步的研究结果,论述了共聚物胶束是起着成核剂的作用,还是起抑制成核作用或对体系的成核行为无影响主要取决于共聚物和均聚物的相对结晶能力及共混体系的相容性.The effect of micelles on nucleation in the crystallization process of dilute poly(tetrahy-drofuran-b-methyl methacrylate) diblock copolymer/tetrahydrofuran homopolymer, dilute po-ly(ethylene oxide-styrene-ethylene oxide) triblock copolymer/ethylene oxide homopolymer solutions has been studied. The results show that nucleation behavior in these solutions is mainly dependent on the relative crystalline ability of the block copolymer and homopolymer, and the compatibility of the blends.
