Three polyvinyl acetate(PVAc) complexes with Fe(Ⅲ), Co(Ⅱ) and Ni(Ⅱ) have been synthesized by the reaction of polyvinyl acetate, respectively, with CoCl₂, NiCl₂ and FeCl₃ in THF at room tempre-ture and one hour was appropriate for reaction. The mole ratio of metal ion to[-CH₂-CH(OCOCH₃)-] segment as found by conductivity measurement was 1:4 in complexes PVAc-Co(Ⅱ) and PVAc-Ni(Ⅱ), but it was 1:3 to 1:6 and more in complex PVAc-Fe(Ⅲ). IR spectra and XPS showed the complex PVAc-Fe(Ⅲ) is formed by non-paired electrons from oxygen atom of CH₃COO group in PVAc with metal ions. TG-DTA revealed the heat stability of complexes was higher than that of PVAc. The proposed structures of the complexes were given.
