The synthesis of biobased aromatic polyesters from lignin-derived monomers has become well described in the literature, but robust extrusion, thermomechanical, tensile and degradation studies of these materials is lacking. In this work, we have systematically investigated the mechanical and biodegradation properties of semi-aromatic polyesters that can potentially be derived from lignin. AB monomers were synthesized from reduced analogues of coumaric, ferulic, and sinapic acids along with cyclic carbonates, where the synthetic methodology was assessed using E-Factor and EcoScale. Polymerization yielded both semi-crystalline and amorphous polyesters with mechanical properties varying over three orders of magnitude. Detailed characterization revealed a wide array of properties including a highly ductile thermoplastic, a strong and rigid thermoplastic, and an elastomer. Composting biodegradation tests showed both degradable and nondegradable polymers can be achieved in this class. This work demonstrates the versatility of this class of polymers and illustrates their potential to replace non-sustainably derived plastics. This journal is

Ferulic acid and p-coumaric acid are abundant, biorenewable precursors for the synthesis of polyethylene ferulate (PEF) and polyethylene coumarate (PEC), as well as cognate copolymers with prescribed hydrogenation of the main-chain double bond. By controlling the comonomer feed ratios, copolymers with tunable thermal properties are obtained, including the thermal range occupied by polystyrene (PS).
