چکیده
|
In this study the modified montmorillonite (omt) was added to poly styrene-co-acrylonitrile (san) and the san/omt nanocomposites were prepared in four compositions, by the melt mixing method# the situation of the layers inside the matrix of the nanocomposites was confirmed by xrd and tem analysis#then, the thermal degradation of san/omt nanocomposites under nitrogen purge at different heating rates was investigated# in this study, the activation energies of san/omt nanocomposites were calculated using flynn wall ozawa method and it was concluded that with increasing of the omt content in nanocomposite, the activation energy values were decreased# it was concluded that clay particles or layers take part in the thermal degradation mechanisms and they must not be regarded as inert materials#
