Cyclic polymers with alternating monomer sequence are synthesized for the ? rst time based on the ring-closure strategy. Well-de? ned telechelic alternating polymers are synthesized by reversible addition–fragmentation chain transfer polymerization by copolymerizing the electron acceptor monomer of  N -benzylmaleimide and donor monomer of styrene with a feed ratio of 1 between them. The corresponding cyclic alternating polymers are then produced by the UV-induced Diels–Alder click reaction to ring-close the linear alternating polymer precursors under highly diluted reaction solution.
