With this award, the Organic and Macromolecular Chemistry Program supports the work of Professor Rudolf Faust, of the Chemistry Department at University of Massachusetts, Lowell, MA. This research will involve detailed investigation of kinetic rate constants for cationic polymerizations and co-polymerizations initiated by Lewis acids. Preliminary data from Professor Faust's laboratory have demonstrated the feasibility of the proposed measurements and have shown that published kinetic data should be carefully reexamined. Ratios of the rate constants of propagation to those of cross propagation will be determined in order to develop a general and quantitative correlation of structure and reactivity in these polymerizations.Knowledge of the structure-reactivity relationship developed in these investigations will allow fundamental control of these polymerizations and lead to the synthesis of new and efficient catalysts. The elucidation of relationships between structure and reactivity in cationic polymerization will enhance teaching and learning by providing a rational foundation for understanding and predicting cationic polymerization behavior.

凭借该奖项，有机和高分子化学项目支持马萨诸塞州洛厄尔市马萨诸塞大学化学系鲁道夫·福斯特教授的工作。 这项研究将详细研究由路易斯酸引发的阳离子聚合和共聚的动力学速率常数。 Faust 教授实验室的初步数据证明了所提出的测量的可行性，并表明应仔细重新审查已发表的动力学数据。 将确定传播速率常数与交叉传播速率常数的比率，以便开发这些聚合中结构和反应性的一般定量相关性。这些研究中开发的结构-反应性关系的知识将允许对这些聚合进行基本控制，并导致新型高效催化剂的合成。 阐明阳离子聚合中的结构和反应性之间的关系将为理解和预测阳离子聚合行为提供合理的基础，从而增强教学和学习。
