摘要
报导了聚乙二醇及其络合物的^(13)C CP/MAS谱并测量了质子旋转坐标系自旋-晶格弛豫时间,结果反映了络合物的相结构或分子堆积结构不同于聚乙二醇。
The 13C CP/MAS spectra of poly (ethylene glycol)and its complexes are reported and their proton frame-rotating spin-lattice relaxation times are also measured. The results show that the phase structures and molecular packing structures of the complexes are different from that of poly (ethylene glycol)
