About the Seminar
"Sustainable aliphatic polyester elastomers"
In this presentation I will discuss our efforts utilizing the controlled ring-opening polymerization of cyclic esters to prepare aliphatic polyester materials that are suitable ingredients for high-performance elastomers. Strategies employing block polymers, chemical cross-linking and polyurethanes will be covered. Keys to the long-term sustainability of these materials include identifying biobased feedstocks for the monomers, simple, efficient, and green polymerizations, molecular architectures that lead to competitive mechanical performance, and facile chemical or biodegradation at the end of life. I will highlight our efforts along these lines and make the case that economically-viable solutions to the current petroleum-derived and non-degradable elastomers are achievable.
