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.

该奖项支持马萨诸塞州洛厄尔马萨诸塞大学化学系鲁道夫·福斯特教授的工作。这项研究将包括详细研究由Lewis酸引发的阳离子聚合和共聚的动力学速率常数。来自浮士德教授实验室的初步数据证明了拟议测量的可行性，并表明应仔细重新检查已公布的动力学数据。将测定传播速率常数与交叉传播速率常数的比率，以建立这些聚合中结构和反应活性的一般和定量关联。了解这些研究中建立的结构-反应关系将允许从根本上控制这些聚合反应，并导致新的和有效的催化剂的合成。阐明阳离子聚合反应中结构与反应活性之间的关系，为理解和预测阳离子聚合行为提供了合理的基础，将有助于教与学。
