Abstract:The electroconductive polymer with new functions and characteristics can be synthesized by electrochemical polymerization. Urushiol is the main component of natural lacquer. There are two phenolic hydroxyls and an unsaturated long alkyl on its benzene ring. According to the structural characteristics of urushiol, by use of electrochemical technique and under controlled conditions, the urushiol oxidized into electropolyurushiol (EPU) film on some double bonds of the long side chain alkyl. Then metallic ion was incorporated into the phenolic hydroxyl to form polymeric chelate compound. So the film of EPU Cu 2+ coordination polymer was obtained by the reaction between CuCl 2 in i PrOH solution and EPU. The EPU Cu 2+ film was characterized by ESR, FT IR, XPS, dynamic mechanical thermal analysis (DMTA) and AES, and the composition and structure of the film were determined. Each Cu 2+ ion is coordinated by hydroxyl from two units in EPU molecule. The Cu 2+ content in the coordination polymer is 8 63%. The experimental results indicated that, the EPU Cu 2+ film activated by Na 2SO 3 can catalyze polymerization of methyl methacrylate (MMA) in water phase at room temperature. The induction period for polymerization is 188 s. The yield of PMMA is equal to about 76%.
Keywords:urushiol  electrochemical polymerization  coordination polymer  coordination catalysis  methyl methacrylate
