摘要 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.
