Radical ring-opening polymerization (ROP) provide a general platform for the synthesis of polymeric materials with complex main-chain functional groups that would otherwise be impossible to introduce through the polymerization of acyclic vinyl monomers. However, existing ROP strategies are still limited to polymerize strained low molecular weight cyclic monomers. Herein, we report a novel chain-growth, triggered ring-opening polymerization (TROP) approach for the rapid and controlled radical polymerization of strainless macrocyclic monomers. Our approach is general and polymerization is amendable for control using various controlled radical polymerization techniques. This polymerization has been used to synthesize block copolymers with other cyclic and acyclic functional monomers. The copolymers achieved high molecular weights, low dispersity, and controlled sequences.
