✦ Synopsis

The solubility behaviour of two paraffin-waxes and two monoglyceride-esters normally used as lubricants in PVC-formulations have been studied with wide-line NMR for rigid and for impact modified PVC. It has been shown that the investigated lubricants have limited solubility in PVC. In the impact modified product, the monoglyceride-esters are partly dissolved in the elastomer phase and partly in the PVC-phase. The paraffin-waxes have limited solubility in the elastomer and in the PVC-phases, and a considerable amount forms a separate phase.

In the two-phase system of PVC-EVA, some co-stabilizers used in connection with metallaurates show a considerable solubility in the elastomer. It is shown that these products can be removed from the soft phase by extraction with petroleum-ether for samples in powdered form. After extraction, the deg
