Living Polyisocyanide Polymerization Catalysts

在有机动力学项目的资助下，麻省大学的诺瓦克教授将设计、制备和研究有机金属催化剂在异氰酸酯和其他不饱和单体的“活性”聚合中的应用。利用新型Ni(I)、Ni（II）、Ni（III）和Pd（II）催化剂的反应性和适用性，合成新型二嵌段共聚物和三嵌段共聚物，用于热塑性弹性体。要测试的前提是聚合物端基的反应性可以以可预测的方式改变以产生独特的物质。这项研究将使用新的催化剂来制备新的含碳聚合物，将其他元素纳入聚合物骨架中。新的热塑性聚合物将被制备出来，其性能在制造汽车、家具等消费品和用于先进技术领域的新材料方面可能被证明是优越的。

With funding from the Organic Dynamics Program Professor Novak of the University of Massachusetts will design, prepare, and study the use of organometallic catalysts for the "living" polymerization of isocyanides and other unsaturated monomers. The reactivity and applicability of new Ni(I), Ni(II), Ni(III), and Pd(II) catalysts will be exploited in order to synthesize novel di- and tri-block copolymers for application as thermoplastic elastomers. The premise to be tested is that the reactivity of polymer endgroups can be altered in predictable fashion to produce unique substances. This research will use new catalysts to prepare new carbon containing polymers that incorporate other elements into the polymer skeleton. New thermoplastic polymers will be prepared whose properties may prove superior in the manufacture of vehicles, consumer products such as furniture, and novel materials to be used in areas of advanced technology.
