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

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
Al~traet--Intrinsic viscosity, sedimentation, light scattering and osmotic pressure measurements have been made on dilute solutions of polycyclohexyl (laCy) and of polyphenyl methaerylates (PPh). Relations between (~), (So), second virial coefficient and molecular weight have been established. The
