核磁共振法测定高聚物的结构—核磁共振二维谱
Structural Analysis of Polymers by Two-Dimensional NMR Spectroscopy
【摘要】 介绍了核磁共振(NMR)波谱,尤其是核磁共振二维谱(2D NMR)在最近几年内的进展。内容包括怎样用NMR测定高聚物的序列分布、共聚物结构、聚合物的混溶性、聚合物液晶的取向度、分子量、短链度和长链支化度、凝聚态高聚物的多相结构等。
【Abstract】 2D NMR A progress in polymer NMR spectroscopy is introdu(?)ed. It comprises how to measure the polymer sequance lengths, the structures of copolymers, the compatibility in polymer, blends, the orientational order of polymer liquid crystals, the molecular weight, the shor-chain and long-cbain branchings, the polymorphs of solid state polymers.
