✦ Synopsis
The interaction energies (X,) between the polymers polypropylene, poly(viny1idene chloride), sulphonyldiphenyl formaldehyde resin and poly(viny1 pyrrolidone) and the solvents toluene, ethylbenzene, isopropylbenrene, ortho, meta, and para-xylene are determined by gas chromatography. As shown in earlier publications, this technique for the determination of X,, can be extended to similar systems of theoretical as well as of practical importance, although the selection of the present systems was primarly made on the fact that these systems are of industrial interest and have not so far been investigated by gas-liquid chromatography. The studies were carried out at two temperatures and the results obtained show a decrease of XI with an increase of temperature.
