    Description / Table of Contents: Gesättigte aliphatische Polyester mit dem aus Stärke erhältlichen 1.4:3.6-Dianhydrosorbit wurden mit PVC gemischt. Die mechanischen Eigenschaften dieser Mischungen wurden mittels Differentialkalorimetrie, Spannungs-Dehnungs-Experimenten und Torsionspendelmessungen untersucht. Polyester mit mehr als vier Methylengruppen in der Säurekomponente sind mit PVC mischbar. Mischungen aus PVC und Poly(1.4:3.6-dianhydrosorbitadipat) sind dagegen unverträglich; sie zeigen für jedes Mischungsverhältnis zwei Glastemperaturen, die bei denen der Reinkomponenten liegen.
    Notes: Saturated aliphatic polyesters with 1.4:3.6-dianhydrosorbitol units were mixed with poly(vinylchloride) (PVC). The mechanical properties of these mixtures were examined by differential scanning calorimetry, stress-strain experiments, and torsion pendulum measurements. Polyesters containing more than four methylene groups in the acid component are compatible with PVC. These polyesters can serve as plasticizers for PVC. On the contrary, mixtures of PVC with poly(1.4:3.6-dianhydrosorbitol adipate) are incompatible; in this case, at any blend composition, the two glass transition temperatures of the pure components are observed.
