New Biobased Polyester Polyols With Tunable T<sub>g</sub> Values From 4-Vinylguaiacol-Derived Monomers. [PDF]
ChemSusChemBiobased low‐molecular‐weight polyesters were obtained by ROCOP of guaiacol‐derived epoxides with cyclic anhydrides. Varying the length of the acyl moieties on the epoxides and the cyclic anhydride structures, it is possible to tune the Tg's within an 80 ºC wide temperature range.
