9310642 Rinaldi This research deals with studies on the application of novel, recently developed nuclear magnetic resonance techniques to polymer structure characterization problems. Simple problems concerning polymer modification chemistry and copolymerization chemistry will be explored initially to allow the nuclear magnetic resonance techniques to be perfected and to provide experience in their application. Later, more complex problems will be investigated. The studies will be conducted by Professor Peter Rinaldi whose specialty is nuclear magnetic resonance spectroscopy and Professor H. James Harwood jointly whose specialty is in synthesizing polymers and applying chemical and physical techniques to problems of polymer microstructure characterization. New nuclear magnetic resonance techniques developed in Professor Rinaldl's laboratory will permit selective observation of structurally important polymer fragments, and will permit extraction of long-range structural information not previously obtainable by other means. These techniques are ideally suited for polymer characterization studies that require the detection of labeled nuclei that are present in low concentration in these polymers. It is expected that these studies will bring forth new information on detailed polymer structure as a function of polymerization method. ***

9310642 Rinaldi这项研究涉及最近开发的新型核磁共振技术在聚合物结构表征问题中的应用研究。初步探讨有关聚合物修饰化学和共聚化学的简单问题，以完善核磁共振技术，为其应用提供经验。稍后，将调查更复杂的问题。这些研究将由彼得·里纳尔迪教授和H·詹姆斯·哈伍德教授共同进行，他们的专长是核磁共振波谱，他们的专长是合成聚合物，并将化学和物理技术应用于聚合物微结构表征问题。Rinaldl教授的实验室开发的新核磁共振技术将允许选择性地观察具有重要结构的聚合物片段，并将允许提取以前通过其他方法无法获得的远程结构信息。这些技术非常适合需要检测低浓度存在于这些聚合物中的标记核的聚合物表征研究。预计这些研究将带来关于聚合方法作用下的详细聚合物结构的新信息。***
