摘要
本文应用GPC、FTIR、TLC、NMR等方法分析、鉴定、研究了实验室自制的PEG-PET嵌段共聚物的嵌段比例、分子量及序列结构,并证实共聚物是一种以PET硬段封端的多嵌段共聚物。
A series of PEG/PET block copolymers are prepared in the laboratory; their segments proper-tion, molecular weights and order structures are determined by GPC, FTIR, TLC, NMR etc. The products are proved to be multiblock copolymers terminated with PET hard segments.
