Lecture
This lecture covers the mechanisms and selectivity of ionic chain polymerization, focusing on anionic and cationic polymerization reactions. It discusses the preferential polymerization of monomers, initiation, propagation, and termination steps, as well as the advantages of using Lewis acids in combination with proton donors. The lecture also includes practical examples and calculations related to the polymerization of 2-methyl-1-butene. Through the analysis of different monomers and reaction conditions, students gain insights into the controlled and selective nature of ionic chain polymerizations.
