In light of fossil fuel depletion and a general necessity for sustainable development, the synthesis of polymers from renewable resources is gaining more and more importance, yet industrially relevant radical polymerizations still struggle with the incorporation of renewable resources as the number of natural molecules containing suitable double bonds is limited. Herein, we present the sustainable synthesis of nonactivated allylic and olefinic carbonate monomers from renewable resources in a solventless one-pot transesterification reaction. We subsequently confirm the first controlled radical copolymerization of such challenging nonactivated monomers with vinyl acetate, in which molecular weights above 10 000 g·mol–1 were reached. The controlled nature of the copolymerizations was verified by the low dispersities obtained and the linear increase in molecular weights with conversion. The so-prepared copolymers were purified using sustainable extractions by supercritical carbon dioxide (scCO2), which allowe...
