Renewable α,ω-diene monomers have been prepared from ferulic acid, biosourced diols (isosorbide and butanediol) and bromo-alkenes using a chemo-enzymatic synthetic pathway then studied as monomers in ADMET polymerization. All monomers and polymers have been thoroughly characterized using NMR, GPC, DSC and TGA. ADMET polymerization was optimized with regard to the catalyst loading (Hoveyda-Grubbs II), the reaction medium (in mass vs. in solvent), and the temperature, and led to polymers with molecular weight up to 25 kDa. Thermal analysis of these new poly(ester-olefin)s showed excellent thermal stabilities (283-370 °C) and tunable <i>T<sub>g</sub></i> depending on the nature of the biobased diol and the chain length of the alkene in the α,ω-diene monomer.
