The focus of this research is to extend diffusion clock methods to determine the rate constant of propagation, ionization (activation) and deactivation in the living polymerization of isobutylene, styrene and styrene derivatives, as a function of solvent, temperature and catalyst. Knowledge of these rate constants is fundamental for overall control in cationic polymer synthesis and also important in new catalyst development.With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Rudolf Faust in the Department of Chemistry at the University of Massachusetts, Lowell. Professor Faust will focus his work on determining the absolute rate constants in cationic polymerization. These studies will promote renewed research in catalyst design and thus lead to the production of more efficient polymerization catalysts.

本研究的重点是扩展扩散时钟方法，以确定异丁烯、苯乙烯和苯乙烯衍生物活性聚合中的传播、电离（活化）和失活速率常数，作为溶剂、温度和催化剂的函数。 了解这些速率常数对于阳离子聚合物合成的总体控制至关重要，对于新催化剂的开发也很重要。有机和高分子化学项目通过该奖项支持了英国大学化学系 Rudolf Faust 博士的研究。马萨诸塞州洛厄尔。 Faust 教授的工作重点是确定阳离子聚合的绝对速率常数。 这些研究将促进催化剂设计的新研究，从而生产出更高效的聚合催化剂。
