요약 | This dissertation focuses on the development of iron-based polymerization catalysts for use in the production of high commodity polymers, polyethylene and poly(lactic acid). Chapter one establishes the current landscape of the plastic market and outlines the advantages to developing iron-based catalysts. Chapter two then explores the use of bis(pyridinylimino)isoindolate-ligated iron complexes as a family of ethylene polymerization catalysts possessing distinctive mechanistic behavior. Chapter three moves to focus on the polymerization of stereoregular poly(lactic acid) from an achiral bis(imino)pyridine-ligated iron precatalyst. The mechanism for the desymmetrization of the catalyst is further detailed, and new avenues for enhancing the behavior of the reaction are discussed. Chapter four details the development of conditions for the rapid chain transfer polymerization of lactide and cyclohexene oxide, offering another tool by which value and complexity may be added to polymerization reactions carried out by this family of bis(imino)pyridine-ligated iron complexes. Finally, chapter five leverages the known redox-switchable features of bis(imino)pyridine-ligated iron complexes to develop reaction conditions for the controlled branching of poly(lactic acid) in a one-pot polymerization reaction. |
