## Abstract For solutions of polystyrene (PS) samples of different relative molecular mass (molecular weight) __M__ and intrinsic viscosities [__n__] have been measured at 298,15 K in pure toluene (T) and toluene/methanol (MeOH) mixtures. Upon mixing toluene (good solvent (1)) and methanol (nonsolv
Intrinsic viscosity measurements were carried out on polystyrene and polyvinylpyridine solutions in various solvents and solvent mixtures. The Stockmayer-Fixman extrapolation was applied to the date: it yields the unperturbed dimensions K s of the chain. A unique value of K e was found for a given p
