The coordination of Cu (Ⅱ) by PAAm was studied by IR,ESR,XPS and electrical conductivity methods. It is concluded that a hydrophobic PAAm-CuCl~2 coordination polymer was formed and in the coordination polymer the metal ion is coordinated with four N atoms of four PAAm chains. From the Shake-up peak observed on XPS spectra of the coordination polymer it can be readily shown that PAAm-CuCl~2 coordination polymer is in high spin state. The surface of the PAAm- CuCl~2 coordination polymer film activated by Na~2SO~3 can initiate polymerization of VAc in water phase at room temperature.The free radical mechanism for catalytic polymerization of VAc is discussed. The induction period for polymerization is three minutes and twenty seconds.The yield of PVAc is equal to about 75%.
