This research deals with various uses of delocalized carbanions in polymer synthesis. For example, they can be used for the preparation of novel monomers, can initiate the polymerization process, or form macromers. The work to be carried out will deal with the preparation of new silarylene and silarylene siloxane polymers with potential utility as photoresists, membranes, and materials resistant to extreme conditions. New catenanes will also be prepared, as will new types of comb polymers and block polymers. The polymerization process itself and the kinetics of propagation will be studied by advanced nuclear magnetic resonance techniques, with particular attention to the early stages of the reaction.

本研究涉及离域碳离子在聚合物合成中的各种用途。例如，它们可用于制备新单体，可引发聚合过程，或形成大分子。即将开展的工作将涉及新型硅芳烯和硅芳烯硅氧烷聚合物的制备，这些聚合物具有光刻剂、膜和耐极端条件材料的潜在用途。还将制备新的链烷，以及新型的梳状聚合物和嵌段聚合物。聚合过程本身和传播动力学将通过先进的核磁共振技术进行研究，特别注意反应的早期阶段。
