ABSTRACTThe techniques of mass-spectrometric thermal analysis, differential scanning calorimetry, differential thermogravimetry, and wide-angle x-ray analysis of thermal and oxidative degradation of two types of fullerene-containing polymer systems (FCPS) were studied: 1) FCPS with covalent interaction of fullerene C 60 with polymers; 2) FCPS representing mixtures of C 60 with polymers in which interaction of components is realized only by means of Van-der-Waals' forces. In both types of FCPS the electron acceptation properties of C 60 are manifested. In some systems of the first type, a great decrease in thermal stability of a polymer component was observed; in systems of the second type the ability of fullerene C 60 to play a role of "trap" of free radicals is especially manifested. The polymer matrix also influences the thermal behavior of fullerene C 60 . In particular, fullerene can serve as a specific "probe" of chemical processes that occur during thermal degradation of a polymer. Different polystyrenes and poly(methyl methacrylate)s containing 1 -10 mass% C 60 (FCPS) were investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
