Abstract: Four new polymeric oxa-thiacrown ethers were prepared by the intramolecular cy-clization of poly (2-chloroethylglycidyl ether) with dimercaptans, which is the most convenient method for synthesizing poly(thiacrownether)s. The poly(thiacrownether)s exhibited excellent complexation properties for noble metal ions such as Au (Ⅲ), Pd (Ⅱ) and Ag(Ⅰ), except Pt(Ⅳ). In addition, the XPS of polymeric thiacrown ether (PC3) and its complexes of Au(Ⅲ) and Pd(Ⅱ) were determined.

Key words: Polymeric thiacrown ether, Complexation, Noble metals
