Synthetic polymer chemistry forms the basis of the plastics, fibres and rubber industries. This project involves the development of improved methods to prepare butyl rubber, a commercially important synthetic polymer that finds widespread application in areas ranging from tires to medical septa to chewing gum. Butyl rubber is prepared by the carbocationic copolymerization of isobutylene and isoprene at -100 deg C. This difficult and challenging reaction requires an initiator that is capable of generating a highly reactive carbocation and stabilizing this species through cation-anion interactions. We propose to develop a new class of cationic initiators for the polymerization of olefins. The new initiators will be designed to potentially facilitate polymerization at higher temperature or permit the production of new types of rubber materials. The research will involve a significant amount of synthetic inorganic and phosphorus chemistry. The partner, Lanxess Inc., is a leader in specialty chemicals producing ca. 150,000 tonnes p. a. of butyl rubber in Sarnia, ON and their Global R&D Centre for Butyl Rubber is located in London, ON.

合成聚合物化学是塑料、纤维和橡胶工业的基础。该项目涉及开发制备丁基橡胶的改进方法，丁基橡胶是一种商业上重要的合成聚合物，广泛应用于从轮胎到医用隔片到口香糖等领域。丁基橡胶是由异丁烯和异戊二烯在-100 ℃下进行碳阳离子共聚而制得的。这种困难且具有挑战性的反应需要能够产生高反应性碳阳离子并通过阳离子-阴离子相互作用稳定该物质的引发剂。 提出了开发一类新型的烯烃聚合阳离子引发剂的设想。新的引发剂将被设计成可能促进在更高温度下的聚合或允许生产新型橡胶材料。这项研究将涉及大量的合成无机和磷化学。 合作伙伴朗盛公司，是一家领先的特种化学品生产商。年产15万吨位于安大略省萨尼亚的丁基橡胶生产基地和位于安大略省伦敦的丁基橡胶全球研发中心。
