The one-pot combination of enzymatic ring-opening polymerization (eROP) and ring-opening metathesis polymerization (ROMP) is successfully established to construct block copolymers. cis-1,4-Diacetoxy-2-butene is employed both as a precursor to initiate eROP of epsilon-caprolactone or 15-pentadecanolide and as a chain transfer agent in ROMP. The obtained polymers are systematically characterized by NMR, GPC, DSC, and microTOF-QII MS. An evaluation of the reaction kinetics indicates the presence of two stages during the one-pot eROP/ROMP process. Compared with cascade methods, this one-pot method exhibits many advantages for preparing well-defined block copolymers, such as mild reaction conditions and the elimination of complex purification steps for intermediates. Thus, this one-pot combination approach has the potential to be widely used in preparing biocompatible polymeric materials, especially for biological and pharmaceutical applications.
