Abstract
Polymers containing cyclohexane ring as a cardo group was prepared by interfacial polycondensation of 1,1-bis(4-hydroxyphenyl)cyclohexane/1,1-bis(4-hydroxyphenyl)-4-methylcyclohxane with adipoyl chloride. The newly generated polymers were characterized by FTIR and NMR spectral analyses. The thermal properties were studied using thermogravimetric analysis and differential scanning calorimetry. Thermal degradation kinetics of methyl substituted and unsubstituted polymers were studied by TGA at different heating rates. The apparent activation energy for the degradation of both the polymers was determined by two different non-isothermal model free kinetic (Friedmann and Flynn-Wall-Ozawa) methods. The results showed that the activation energy of the polymers with methyl substituent in cyclohexane is higher than unsubstituted polymers.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
