By reaction of urushiol and MoOCl\-4, the urushiol\|molybdenum chelate polymer was prepared which possessed properties of lacquer and chelate. This reaction forms non\|dissolving,non\|melting and black precipitates of urushiol\|molybdenum chelate polymer.The Mo percentage by weight of polymer prepared by different reaction condition was measured. The reaction mechanism,structural characteristics and properties of the polymer were also investigated. The polymer has been characterized by ESR,XPS,GPC,IR,MS,TG and elementary analysis. The results have confirmed that the redox reaction, coordination reaction and then polymerization occur in the process of formation of the polymer. The moiety of (C\-\{21\}H\-\{30\}O\-2)\-2MoOCl exists in the polymer. ESR analysis showed the atom Mo in the polymer exists in 5\|valence. TG analysis shows that the polymer exhibits good resistance to heat.
