Comprehensive Revision of Rate Constants in Cationic Polymerization

有了这个奖项，有机和高分子化学计划支持鲁道夫浮士德教授，化学系在马萨诸塞州，洛厄尔，马萨诸塞州大学的工作。 本研究将详细探讨由刘易斯酸引发的阳离子聚合及共聚反应的动力学速率常数。 来自浮士德教授实验室的初步数据已经证明了拟议测量的可行性，并表明应仔细重新审查已发表的动力学数据。 将确定传播的速率常数与交叉传播的速率常数的比率，以便在这些聚合反应中建立结构和反应性的一般和定量的相关性。在这些研究中建立的结构-反应性关系的知识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性之间的关系，为理解和预测阳离子聚合反应行为提供了合理的基础，从而提高了教学效果。

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.
