Abstract

Techniques regarding catalyzing one or more ring-opening polymerizations within one or more flow reactors using one or more organometallic bases are provided. For example, one or more embodiments described herein can comprise a method, which can include forming a polymer, via a ring-opening polymerization within a flow reactor, from a cyclic monomer in the presence of an organometallic base and a primary alcohol initiator.
