Scaling theory is applied to derive expressions describing the influence of polymolecularity on the second virial coefficient, A , , as obtained from osmotic pressure and light scattering measurements. Numerical values of polymolecularity correction factors are calculated for Schulz-Zimm and logarit

Abstract
It is shown that the recently developed scaling theory for the second virial coefficient, A~2~, of dilute solutions of polymers with nonβuniform molecular weight distributions in a good solvent is able to explain in principle all seemingly contradictory observations reported in the literature, in contrast to all other theories proposed so far.

Based on the measurement of the concentration dependence of the osmotic pressure of sodium alginate aqueous solution in different concentrations of potassium nitrate, the contribution of polyion charges to the second virial coefficient was predicted. According to this analysis, an equation A 2 = A 2
## Abstract A simple modification of the Pitzer relation to calculate second virial coefficients of polar compounds is proposed. The proposed modification is based on the use of a new parameter, Ξ², which embodies both the contributions of acentricity and polarity to second virial coefficient values
