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

## 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
