Nuclear Magnetic Resonance Studies of Polymers and Polymer Intermediates

9310642 Rinaldi本研究涉及最新发展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。初步探讨聚合物改性化学和共聚化学方面的简单问题，使核磁共振技术得到完善，并为其应用提供经验。稍后，将研究更复杂的问题。研究将由Peter Rinaldi教授（专长于核磁共振波谱学）和H. James Harwood教授（专长于合成聚合物并应用化学和物理技术解决聚合物微观结构表征问题）共同进行。里纳尔德教授实验室开发的新核磁共振技术将允许对结构上重要的聚合物碎片进行选择性观察，并允许提取以前用其他方法无法获得的远程结构信息。这些技术非常适合于需要检测这些聚合物中低浓度存在的标记核的聚合物表征研究。预计这些研究将为聚合方法的详细聚合物结构提供新的信息。＊＊＊

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. ***
