以PBT和PEG大分子单体为原料，通过大分子酯交换法合成了水解可降解的PBT/PEG共聚物。所得共聚物通过 H-1-NMR 和 GPC 进行了表征。通过差示扫描量热法（DSC）研究了这些共聚物的非等温结晶行为。还详细研究了PBT/PEG共聚物的吸水性和水解降解行为。
Hydrolytic degradable PBT/PEG copolymer was synthesized by macromolecular transesterification method from PBT and PEG macromonomers. The resultant copolymers were characterized by H-1-NMR and GPC. The non-isothermal crystallization behavior of these copolymers was studied by differential scanning calorimetry (DSC). The water absorption and hydrolytic degradation behavior of PBT/PEG copolymers were also studied in detail.
