The thermal degradation behavior of poly(alkyl methacrylate) and conducting polymer, poly(chloro phenyl acetylene)(PCPA) mixture was analyzed using the gel permeation chromatography(GPC), pyrolysis gas chromatography(PGC) and thermog-ravimetric analyzer(TGA) under nitrogen gas flow of 30 ml/min at various heating rates ranging from 4 to 20℃/min. According to increasing temperature and frequency, electrical properties were analyzed using the LCR meter and electrometer. The morphological analysis at interface of mixture was carried out using the scanning electron microscopy(SEM) and energy dispersive spectrometer(EDS). The values of activation energy of thermal degradation in the mixture determined using the Fried-man's method were 37∼61 Kcal/mol. The thermal degradation mechanism of PMMA and PCPA mixture was observed to be main chain scission under nitrogen environment. The values of activation energy using electric conductivity determined above and bellow of the glass transition temperature were 0.501∼0.848 eV and 0.201∼0.451, respectively.
