The homopolymer (PANI) and its homologue PANI–PEO2000 copolymer have been prepared under effect of Maghnite-H+ (Algerian MMT) in different weight percentages (wt%) by cationic polymerization method. The formation of the hydrogen bonding between PANI and PEO2000 and structure of PANI are predicted by the FT-IR and 1HNMR spectra. Glass transition temperature of pure PANI and pure PEO2000 are, respectively, Tg = 74 °C and Tg = 65 °C, but DSC analysis for the copolymer (PANI–PEO2000) showed only one (Tg = 16.79 °C) implying compatibility of PANI and PEO2000. Here we can suggest that under suitable condition (the amount of catalyst, molecular weight and functionality of the reactive stabilizer (PEO2000) and molar ratio of (PANI/PEO2000), our catalyst can improve the morphology, structure and chemical properties of PANI and its homologue PANI–PEO2000.
