9617477 Rinaldi In this grant, two- and three-dimensional nuclear magnetic resonance (NMR) triple techniques (together with isotropic labeling in some cases) are being used to study problems in polymer structure, polymer formation and degradation mechanisms, and polymer reactivity. Methods which have been used for years in structural biology are being adapted for application in polymer science and new methods are being developed which are uniquely suited for the study of polymers. These methods allow selective probing of the structure and transformations which occur in one small part of a large molecule without interference from the signals from the rest of the molecule. %%% These techniques are being used to study the structure of polymer block junctions, polymer chain ends and defects, and the mechanisms of various polymer reactions. A knowledge of these structures provides valuable insight into polymer formation and stability. The materials being studied are important for the manufacture of rubber products, plastics, semiconductors, and biomedical engineering materials. ***

小行星9617477 在这项资助中，二维和三维核磁共振（NMR）三重技术（在某些情况下与各向同性标记一起）被用于研究聚合物结构，聚合物形成和降解机制以及聚合物反应性中的问题。 在结构生物学中已经使用多年的方法正在适应聚合物科学的应用，并且正在开发独特地适合于聚合物研究的新方法。 这些方法允许选择性地探测大分子的一小部分中发生的结构和转化，而不受来自分子其余部分的信号的干扰。 这些技术正被用于研究聚合物嵌段连接的结构、聚合物链端和缺陷以及各种聚合物反应的机理。 这些结构的知识提供了有价值的洞察聚合物的形成和稳定性。 所研究的材料对于橡胶制品、塑料、半导体和生物医学工程材料的制造非常重要。 ***
