Abstract:
In this work, polystyrene/waste tires composites were prepared using the melt-mixing method.. The effect of the preparation conditions of the PS/waste tires composite is investigated in this work by using Gel permeation chromatography (GPC) technique.
Stability at elevated temperatures were found to increase with the addition of waste tires to PS as confirmed by the results.
GPC results indicate that the preparation conditions of the PS/waste tires composite has no effect on the Ps chains as indicated by GPC technique. The signals of the GPC for unfilled and filled PS are similar. That evidences no thermo-mechanical chain degradation is taken place during the addition of the waste tires under the conditions of the melt-mixing process
