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
Intrinsic viscosity, light scattering, and sedimentation data are reported for fractions of polytert.butylacrylate in different solvents and in a 0-solvent. The unperturbed dimension has been calculated by various methods; the Stockmayer-Fixman and Kurata-Stockmayer relationships gave the best fit f
