Fully Recyclable, Unsaturated Polyesters from Biomass via High Yield, Catalytic Polymerization Reaction
A new polymerization method that produces polyesters from bioderivable starting materials. The polyesters are unsaturated and may easily be further functionalized post-polymerization through cross-linking or other reactions with the unreacted vinyl group. Possible applications in biomedical, biodegradable polyesters, and thermally recyclable plastics...
