中文摘要：

制备了部分醇解的PVA（paPVA），将其与PDO在均相本体接枝聚合，通过对paPVA醇解度以及投料比的选择，得到了具有各种分子结构的接枝共聚物。通过一维核磁共振谱表征了聚合物的微观结构；采用TG、DSC等测试手段研究了接枝共聚物的热性能和结晶性能。

英文摘要：

The partially alcoholysized PVA（paPVA） was prepared and was graft copolymefized with PDO in homogeneous bulk state. By adjusting the degree of alcoholysized PVA and PDO feed ratio, paPVA-g-PPDO copolymers with different molecular structures were achieved. The molecular structures of the eopolymer were characterized by ^1H-NMR spectroscopy. The thermal properties,crystallization behaviors of eopolymer were investigated by differential scanning calorimetry（ DSC ）, thermogravimetry analysis （TGA）.
