Radical coupling copolymerization (RCCP) for synthesis of various polymers

- Radical coupling copolymerization (RCCP) of various pairs of in-situ formed benzyl-type biradicals in the presence of Cu/ligand was realized.
- The monomer sequence distributions and compositions of copolymers were measured by 1H NMR.
- RCCP can be employed to synthesize some new kinds of polymers under mild condition and within a short time.

We report radical coupling copolymerization (RCCP) of various pairs of in-situ formed benzyl-type biradicals derived from dibromides in the presence of Cu/ligand. The monomer sequence distributions and compositions of copolymers were measured by 1H NMR. RCCP can be employed to synthesize some new kinds of polymers, such as polyether, polysulfone and poly(substituted arylene), under mild condition and within a short time. Copolymers with higher molecular weights than the corresponding homopolymers prepared by radical coupling polymerization can be obtained by some pairs of monomers.
