PVC/PMMA keverékek reológiai viselkedésének összehasonlítása

Abstract

The effect of processing temperature on the melt flow PVC blends has been studied with a wide shear rate range. For those blends were prepared at lower temperatures higher melt viscosity could be observed. In this paper, comparison the rheological behaviour of neat PVC and PVC/PMMA blends. In the PVC melt changes depends on the simple flow and temperature loads. We were observed the rheological values changes at different production temperature ranges. The result of the measurements can be inferred from the processing and structural modifications. By temperature increasing the processing type and the temperature can be determined. Based on results of the tests, it can be concluded that the foam parameters, as well as compatibility between PVC and PMMA.
