| 摘 要： | 报道了对嵌段共聚物结晶型共混体系结晶行为的研究．通过对聚甲基丙烯酸甲酯－聚四氢呋喃两嵌段共聚物／聚四氢呋喃共混体系的研究，我们发现１．微相分离结构的存在，可使相容的这类体系形成多种特殊的结晶形态；２．共混体系的相容性可以方便地由其结晶行为来判断；３．共混体系中共聚物的结晶能力显著提高．这些特点都明显不同于一般的聚合物共混体系．

| Abstract: | n the present work, the compatibility and crystallization of methyl methacrylate-tetrahydrofuran diblock copolymer/tetrahydrofuran homopolymer blends were studied. We found that some special crystalline morphologies could be formed for the compatible blends due to the ealstence of microphase separation of the copolymer, and that the dissolution of the homopolymer in its corresponding copolymer domain could detendned by the DSC thermograms of the blends. |
