Description
The dynamics of molecules of arbitrary volumes, dissolved in amorphous polymers, within the glass transition range, is studied within the free volume approximation. A generalized WLF equation is derived. As an application, the temperature dependence of the extreme line separation, for nitroxide like free radicals, within the glass transition range, is derived.
