本工作将Leibler、Whitmore和Mayes等近期关于非晶嵌段共聚物共混体系胶束理论应用于结晶嵌段共聚物共混体系的熔融态,对聚甲基丙烯酸甲酯-聚四氢呋喃两嵌段共聚物与聚四氢呋喃均聚物共混体系的结晶行为进行了研究.结果表明,很低的共聚物浓度(如1％),其胶束在共混体系的结晶过程中即可显著地起到抑制成核的作用.这对改善结晶均聚物的形态及性能有一定的应用价值.
In this work, Leibler, Whitmore and Mayes et al. Recently applied the micelle theory of amorphous block copolymer blends to the melt state of the crystalline block copolymer blends. The effects of poly (methyl methacrylate) - polytetrahydrofuran diblock Copolymer and polytetrahydrofuran homopolymer blend system was studied.The results show that the low copolymer concentration (such as 1%), the micelles in the blending system can be significantly during the crystallization process Inhibit the nucleation effect.This has some application value to improve the morphology and properties of the crystalline homopolymer.
