These files contain primary data along with associated output from instrumentation supporting all results reported in the referenced manuscript. Findings include: an alternate route to tunable, recyclable polyesters derived from CO2 and butadiene via an intermediary lactone, 3-ethyl-6-vinyltetrahydro-2H-pyran-2-one. Catalytic ring-opening polymerization of the lactone by 1,5,7-triazabicyclo[4.4.0]dec-5-ene yields polyesters with molar masses up to 13.6 kg/mol and pendent vinyl sidechains that can undergo post-polymerization functionalization. The polymer has a low ceiling temperature of 138 ºC, allowing for facile chemical recycling. These results mark the first example of a well-defined polyester derived solely from CO2 and olefins, expanding access to new feedstocks that were once considered unfeasible.
Each type of data is collected in a single main folder (e.g., NMR, SEC dRI, etc.) and then separated into corresponding folders.
The funding for this work was provided by the NSF Center for Sustainable Polymers (CHE-1901635) at the University of Minnesota. Instrumentation for the University of Minnesota Chemistry NMR facility was supported from a grant through the National Institutes of Health (S10OD011952).
