Cyclopolymerization, which does not need a cyclic derivative as monomer, is a direct method for producing rings and polymer chain at the same time. Monomers forming 5-7 membered-rings have been generally studied. We established the synthesis of polymers with macrocyclic units via cyclopolymerization of bifunctional monomers containing oxyethylene units. Poly (crown ether) s and poly (cryptande) s are synthesized through the polymerizations of divinyl ethers and diepoxides, poly (thia-crown ether) s through diepisulfides, and poly (crown lactone) s through the monomers having acrylic and allylic groups. These polymers except for poly (crown lactone) s consist essentially of cyclic constitutional repeating units, and have the cation-binding properties. Cyclopolymerization of divinyl ethers is a facile method for producing optically active poly (crown ether) s which exhibit chiral recognition towards α-amino acids. For the cyclopolymerization of divinyl ether derived from chiral 3, 3'-disubstituted- 1, 1'-bi-2-naphthol, the asymmetric induction in the polymer main chain was concluded by the analysis of 1H NMR spectra of polymers.
