Abstract: Three novel poly thiacrown ethers with polymeric thiaether crosslinked chain were pre-pared in moderate yield by condensation of poly(chloromethylthiirane) with dimercaptans.Thepolymer strongly complexed with Ag+ and Au2+, but did not forms complexes with Pb2+,Mg2+, K+ and Na+.

Key words: polythiacrown ether, macrocyclic polythiaether, complexability
