Mathieu J.-L. Tschan,Jia Guo,Sumesh K. Raman,Emilie Brulé,Emilie Brulé,Thierry Roisnel,Marie-Noëlle Rager,Rémi Legay,Guillaume Durieux,Baptiste Rigaud,Christophe M. Thomas +10 more
TL;DR: The coordination chemistry of a series of pro-ligands ([L¹]-[L⁶]) with cobalt and zinc derivatives has been studied to yield polymers under solvent free conditions with controlled molecular masses and narrow polydispersities.
Journal ArticleDOI
Waste not, want not: CO2 (re)cycling into block polymers
TL;DR: A new way to combine two different polymerisation reactions, using a single catalyst, results in efficient block polymer synthesis with an atom economy of up to of 91%.
Journal ArticleDOI
Ultrarapid Cerium(III)–NHC Catalysts for High Molar Mass Cyclic Polylactide
Ryan W. F. Kerr,Ryan W. F. Kerr,Ryan W. F. Kerr,Paul M. D. A. Ewing,Paul M. D. A. Ewing,Sumesh K. Raman,Andrew D. Smith,Charlotte K. Williams,Polly L. Arnold +8 more
TL;DR: In this article, cyclic polyesters could improve the properties of degradable plastics, but routes to them that provide a product with faster rates, higher molar mass, and greater selectivity for cyclic vs linear p...
