| 摘 要： | 报导了系列聚四氢呋喃-聚甲基丙烯酸甲酯结晶-非晶(硬段型)两嵌段共聚物的结晶行为，结果表明，其微相分离和结晶规律与文献上唯一进行过系统研究的同类嵌段共聚物(PEO－b－PS)都有较大的差别；结晶段结晶能力的大小是制约这类体系微相分离和结晶规律的一个重要因素．

| Abstract: | Crystallization behavior of a series of newly synthesized poly (tetrahydrofuranb-methyl methacrylate) diblock copolymer has been studied by differential scanning calorimetry (DSC) and X-ray scattering and diffraction techniques. The results show that the microphase separation and crystallization are very different from that of poly (ethylene oxid-b-styrene) diblock copolymer, the only one systematically investigated in literature. Our results suggeste that crystalline ability of the crystallizable block of such type of diblock copolymer is one of the important factors governing its microphase separation and crystallization. |
