The preparation of Cu (II)-poly (vinyl alcohol) (abbreviated as PVA) complex was carried out changing the molar ratio of Tcu2+/THL (Cu (II) ion to monomer unit of PVA) in aqueous solutions at 25°C. The resulting solutions were allowed to stand for 24hr. at 25°C, and then dialysed to remove excess reagents. The complexes films were obtained from these solutions by casting on to polyethylene films. We studied thermal decomposition of the complex films of Cu (II) ion with PVA by pyrolysis gas chromatography. The metal chelate moiety in Cu (II)-PVA films apparently catalyzes oxidation during pyrolysis of PVA and the formation of CO and CO2 may be increased.
