A family of renewable macrobis- and trisphenols containing bio-based polyols and ferulic acid, derived respectively from plant polysaccharides and lignocellulose, was prepared through a chemo-enzymatic process under mild conditions. The lipase-catalyzed condensation step can be conducted in bulk as well as in solvent and leads to high purity grade macromonomers in high to excellent yields.?? These bio-based macrobisphenols were then used as macromonomers for the preparation of (1) alternating aliphatic/aromatic copolyesters, (2) aliphatic/aromatic polyurethanes, and (3) linear homogeneous phenolic homo-oligomers through an oxidase-mediated aryl-aryl coupling.The newly obtained aliphatic/aromatic homo- and copolymers were characterized by GPC, thermal (DSC) and thermogravimetric analyses (TGA). These analyses revealed not only good thermal stabilities but also a broad range of accessible glass transition temperatures (Tg).
