    Description / Table of Contents: Results are reported on incompatibility measurements of a high molecular weight polystyrene (PS) and poly-α-methylstyrene (P-α-MS) in the nearly isorefractive polymer/solvent mixtures polyisobutylen (PIB)/benzene by means of the light scattering method. It turns out that the degree of compatibility of both systems, PS/PIB/benzene and P-α-MS/PIB/benzene is nearly equal and very low. The measurements of the cloud points agreed very well with these results. Measurements with other polymer systems allowed to predict the equality of the compatibility of PS and P-α-MS with PIB; the degree of incompatibility, however could not be predicted.
    Notes: Ein hochmolekulares Polystyrol (PS) und ein Poly-α-methylstyrol (P-α-MS) wurden im nahezu isorefraktiven Polymer-Lösungsmittel-Gemisch Polyisobutylen (PIB)/Benzol mittels Lichstreuung untersucht. Es zeigte sich, daß die Verträglichkeits-grade beider Systeme PS/PIB/Benzol und P-α-MS/PIB/Benzol etwa gleich und sehr gering sind. Messungen der ersten visuellen Trübungspunkte bestätigen dies. Aufgrund früherer Untersuchungen mit anderen Polymersystemen konnte die Gleicheit der Verträglichkeitsgrade von PS und P-α-MS mit PIB, jedoch nicht die Große der Unverträglichkeit, vorausgesagt werden.
