Enzymatic synthesis and characterization of muconic acid‐based unsaturated polymer systems
Abstract The design of unsaturated aliphatic (co)polyester systems, based on different diester‐modified muconic acid isomers, was performed via an eco‐friendly pathway by utilizing enzymatic polymerization using Candida antarctica lipase B (CALB) as catalyst. The obtained fully unsaturated oligoeste...
