The PVP-Cu(Ⅱ) and Al(Ⅲ) complexes formed were most stable in the pH range from 3 to 5. The viscosity of the PVP-Cu(Ⅱ) complex wart lower than that of PVP-AI(Ⅲ) complex because the conformation of the former is more compact than that of the latter. The catalytic activity of PVP-Cu(Ⅱ) and -Al(Ⅲ) in decomposition of hydrogen peroxide was increased with an increase of complex concentration and reaction time. The PVP-Cu(Ⅱ) complex exhibited specific resistivity of around 10₄-cm when modified iodine in acetone. It was also observed that resistivity of complex formed at pH in the range of 3 to 5 was low.

PVP-Cu(Ⅱ) 및 PVP-Al(Ⅲ) 착물은 pH 3-5영역에서 가장 잘 형성되고, pH에 따라 Cu(Ⅱ) 착물히 PVP-Al(Ⅲ) 착물보다 상대점도비가 낮다. 이는 PVP-Cu(Ⅱ) 착불의 구조가 보다 compact 하기 때문이다. 과산화수소의 분해반응에 따른 PVP-Cu(Ⅱ) 및 Al(Ⅲ) 착물의 촉매활성도는 착물의 농도가 증가하고 반응시간이 길수록 증가하였다. 또한 요드로 doping 한 PVP-Cu(Ⅱ) 착물의 전기저항은 10⁴Ω-cm이고 pH 3-5 영역에서 제조한 착물의 저항값이 낮음을 실험결과 알았다.
