With the use of the Flory-Krigbaum interaction potential between the polymersolutes, virial coefficients are calculated up to the fifth order. Both the fourthand fifth virial coefficients can take not only positive values but also negative ones.The osmotic pressure obtained from these virial coefficients is compared withexperimental data. In low concentration, calculated results agree with the experi-mental data quantitatively. The limit of concentration up to which the resultsagree with the experimental datx becomes clear by the calculation of the fourthand fifth virial coefficients.
