| Abstract: | Abstract The mechanical properties (dynamical, tensile) and morphology by electron microscopy have been studied on PVC mixtures with processing aids of different compatibility with PVC (copolymers of methylmethacrylate, polystyrene, polyvinylacetate) in the temperature range of 20-150°C. It has been found and interpreted that the mechanical properties of PVC in the temperature range of 100-120 °C are favourably influenced by addition of a processing aid, which is compatible with PVC, has a sufficiently high molecular weight and its glass temperature is about 20°C higher than that of PVC. |
