摘要
用NMR、MS、TEM研究了未知物ES-PU聚氨酯的组成、结构与微观形态,指认了NMR吸收峰,讨论了聚氨酯“硬段畴”结构并提出了氢键形成的模型。
The composition, structure and micromorphology of unknown ES-PU polyurethane were studied by means of NMR, MS and TEM. We identified NMR absorption peaks, studied 'hard segment domains' and offered the model of formation of hydrogen bonding.
