'Duranes': Ultrahard High-Strength Organic Polymeric Materials

小行星9704143 该项目将开发一种新的方法来扩展网络，非常高强度的有机聚合物材料。 其中一些材料将是超硬的，其他的将是“有机沸石”。 将采取三种办法：（a）制备新的聚合物和共聚物，（一种在约220 ℃下变得具有反应性的烃）是侧基，（B）制备新的聚合物，其中七曜烯进行环加成聚合以形成主链，和c制备基于可逆Diels桤木聚合和基于七曜烯环加成二聚反应的新的扩展网络聚合物，以及多聚环加成至C60。 一旦准备好，新的聚合物材料将使用材料科学和实验凝聚态物理学的最新技术确定其机械，光学和电子特性。 这些新的聚合物材料应该具有作为强度接近金刚石的结构材料作为催化剂载体等的潜在应用，并且可以为合理设计的三维扩展固体的新家族打开大门。 ***

9704143 Wudl This project will develop a new approach to extended-network, very high strength organic polymeric materials. Some of these materials will be ultrahard, others will be "organic zeolites:. Three approaches will be pursued: (a) preparation of new polymers and copolymers where pleiadene (a hydrocarbon which becomes reactive at ca 220 degrees C) is a pendant group, (b) preparation of new polymers in which pleiadene undergoes cycloaddition polymerization to form the backbone, and c preparation of new extended network polymers based on reversible Diels Alder polymerizations and on the pleiadene cycloaddition dimerization reaction and multiple cycloaddition to C60. Once prepared, the new polymeric materials will have their mechanical, optical and electronic properties determined using the latest techniques in materials science and experimental condensed matter physics. %%% These novel polymeric materials should have potential applications as structural materials of strengths approaching diamond as catalyst supports, etc., and may open the door to new families of rationally designed, three-dimensional extended solids. ***
