Abstract

The prepared polystyrene has weaknesses in terms of mechanical, physical and thermal properties which limits the use of this polymer.Therefore, the use of the mixtures of polymers can improve these properties.Different parameters like the mixing speed can affect the quality of the properties of preparing polymer from the mixture of several polymers. In this study, different percentages of nanocomposites in different stirring speeds have been added to polystyrene. Different tests have been performed on prepared polymer that investigating the tests shows in different stirring speeds the value of tensile and impact resistance of prepared polymer can be increased while the value of the Vicat Softening Temperature (vicat) and Melt Flow Index (MFI) test number remain constant. The obtained results from laboratory data have been simulated by Artificial Neural Networks (ANNs) in order to predict the results for points which has not been tested and the simulated results show that the laboratory data covered simulated data perfectly.
