The thermal degradation of the homopolymer poly(methyl methacrylate)(PMMA)/tetra cyano quino dimethane(TCNQ) blend and Eccogel/TCNQ blend were carried out using the thermogravimetric method in the stream of nitrogen gas with 60ml/min at various heating rate from 1 to $20^{circ}C/min$. Friedman and Ozawa mathermatical methods were used to obtain the value of activation energy. Produced electrical properties and activation energy by electric conductivity method that used LCR meter
