Kinetic Strategies for Synthesis of Olefin Copolymers of Defined Sequence Distribution

本研究的重点是制备和研究含有至少两个活性位点且共聚特性不同的新型桥接茂金属，以制备交替共聚物或嵌段共聚物。这项工作的目标是开发一个新的乙烯/ α -烯烃共聚物家族，并将研究作为一个试验场，以评估控制共聚特性的茂金属催化剂的精确结构特征。通过这个奖项，有机和大分子化学项目支持了斯坦福大学化学系Robert M. Waymouth博士的研究。Waymouth教授将致力于开发一种新的合成顺序分布可控的烯烃共聚物的动力学策略。由于有可能控制新材料的制备，该研究对聚合物工业具有重要的影响。

The focus of this research is the preparation and study of new bridged metallocenes containing at least two active sites that differ in their copolymerization characteristics in order to produce alternating or blocky copolymers. The goals of the work are to develop a new family of ethylene/alpha-olefin copolymers of defined sequence distribution and to use the studies as a testing ground to evaluate the precise structural features of metallocene catalysts that control copolymerization characteristics.With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Robert M. Waymouth of the Department of Chemistry at Stanford University. Professor Waymouth will focus his work on developing a new kinetic strategy for the synthesis of olefin copolymers of controlled sequence distribution. With the potential for the controlled preparation of new materials, the research has important ramifications for the polymer industry.
