Chemoenzymatic synthesis of polymeric materials using lipases as catalysts: a review

Abstract

In the past two decades, enzymatic polymerization has rapidly developed and become an important polymer synthesis technique. However, the range of polymers resulting from enzymatic polymerization could be further expanded through combination with chemical methods. This review systematically introduces recent developments in the combination of lipase-catalyzed polymerization with atom transfer radical polymerization (ATRP), kinetic resolution, reversible addition-fragmentation chain transfer (RAFT), click reaction and carbene chemistry to construct polymeric materials like block, brush, comb and graft copolymers, hyperbranched and chiral polymers. Moreover, it presents a thorough and descriptive evaluation of future trends and perspectives concerning chemoenzymatic polymerization. It is expected that combining enzymatic polymerization with multiple chemical methods will be an efficient tool for producing more highly advanced polymeric materials.
