Notes:
The Gibbs energy of adsorption, the Flory-Huggins interaction parameter χ, and a specific interaction parameter A, based on hydrogen-bonding and charge-transfer complexing properties of solvents, are obtained by gas - solid chromatography for a type of polyquinoxaline denoted as PQF. Interactions between 40 organic solvents and PQF have been determined at 176.35° and 200.85°C. PQF is an aromatic, heterocyclic polymer which is at least partially soluble in several organic solvents. The parameters χ and Λ and the solubility parameters of solvents are proposed to be the determining factors for miscibility of a PQF - solvent pair.
