Studies on the Coordination Polymer of Copper Electropolyurushiol

The coordination polymer of copper electropolyurushiol(EPU-Cu2+) was obtained by the reaction of copper chloride with electropolyurushiol (EPU) in an isopropyl alcohol solution. The properties of EPU-Cu2+ were studied by means of ESR, FTIR, XPS, DMTA and TG-DTA.The results of AES show that the content of Cu2+ was 8.63%. The electric resistances of EPUCu2+ and EPU were determined to be 9.37×1010Ω and 7.90×1010Ω respectively. It was also ascertained that in EPU-Cu2+ each Cu2+ is coordinated with two units hydroxyl in EPU, making the EPU-Cu2+ 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.
