The properties of EPU-Cu^(2+) were studied by means of ESR, FTIR, XPS, DMTA and TG-DTA. The results of AES show that the content of Cu^(2+) was 8.63%. The electric resistances of EPU-Cu^(2+) and EPU were determined to be 9, 37×10^(10) Ω and 7.90×10^(10) Ω respectively. It was also ascertained that in EPU-Cu^(2+) each Cu^(2+) is coordinated with two units hydroxyl in EPU, making the EPU-Cu^(2+) cross-link further. As a result, the title polymer exhibits an insolubility in most of organic solutions, a higher glass transition temperature and thermal resistance.展开更多
