Catalytic Activation of Renewable Resources - Professor Charlotte Williams - CPS 2021

The lecture will describe recent research from the Williams group on developing new catalysts that activate renewable resources like plant derived bio-chemicals and carbon dioxide to make polymers. The first part of the lecture will introduce the catalyses (cyclic lactone ring-opening polymerization and epoxide/carbon dioxide/cyclic anhydride ring opening copolymerizations). It will provide a recent case study on how heterodinuclear synergy can be exploited to make highly active catalysts for carbon dioxide copolymerization. In the second part of the lecture, the importance of these catalysts and polymers will be illustrated with case studies showing the preparation of ductile plastics, thermoplastic elastomers and polymer pressure sensitive adhesives. In this part, the polymer structure and property relationships will be explored, in particular how the precise placement of carbon dioxide in the chemical structures can be used to alter and tune properties for specific applications. The lecture will close with an examination of the future challenges in this field and opportunities for problems to solve. This talk was delivered by Professor Charlotte Williams from Oxford University to the audience of the public, CPS members, and UCL staff and students on the 10th March 2021.
