Comprehensive Revision of Rate Constants in Cationic Polymerization

通过这个奖项，有机和大分子化学项目支持了马萨诸塞大学洛厄尔分校化学系Rudolf Faust教授的工作。这项研究将包括详细研究由路易斯酸引发的阳离子聚合和共聚合的动力学速率常数。Faust教授实验室的初步数据证明了所提议的测量方法的可行性，并表明已发表的动力学数据应该仔细重新检查。为了在这些聚合中建立结构和反应性的一般和定量的相关性，将确定繁殖速率常数与交叉繁殖速率常数的比值。在这些研究中发展的结构-反应关系的知识将使这些聚合的基本控制，并导致新的和高效的催化剂的合成。阐明阳离子聚合的结构与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，从而提高教学质量。

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.
