Bioderived monomers, readily available from biomass via atom- and redox-efficient processes, will need to play a major role in the development of sustainable polymeric materials. Here, we show that family tricyclic efficiently made biobased furans Diels-Alder chemistry, allows production polyenes with diverse thermo/physical properties through ring opening metathesis polymerization (ROMP). Via small structural variations, offer insight into intricacies monomer design its implications for polymerization. Notably, thermostable all very similar head-to-tail regioregularities, trans-linkage isomerism distributions, narrow dispersities. Additionally, monomers exhibit rare reactivity ethyl vinyl ether, which can be used as chain transfer agent, enabling synthesis monotelechelic polyenes. The do differ substantially rate, spanning two orders magnitude, extent molecular weight control resulting amorphous polymers. With glass transition temperatures ranging 116 217 °C degradation exceeding 350 °C, these materials are among highest performing homopolymers reported. We elucidate demonstrating ROMP is profoundly influenced by subtle changes monomers.
