✦ Synopsis

Pair interaction parameters like the second virial coefficient A z or the Flory-Huggins parameter Z are influenced by inter-and intramolecular contacts. The paper discusses a model in which A 2 linearly depends on M -~" 0.5), where a is the exponent in the Mark-Houwink relation. From this dependence, the two components of Z, namely Z~nter and ~intra, were evaluated and their values, their interdependence and their variation with the thermodynamic quality of the solvent were determined. The evaluation of numerous literature data confirms the model.
