Abstract:
Polystyrene/waste tires composites were prepared in this study by incorporating small particles of waste tires into polydisperse commercial polystyrene (PS) in a melt-mixing method. The dynamic mechanical properties of PS and PS/composite were studied using ARES-Rheometer under nitrogen atmosphere in parallel plate geometry with diameter 8 mm. The measurements were carried out over a wide range of temperatures ranged from 120°C to 220°C and frequencies from 100 to 0.1 radians per second. The shear compliance of PS composite were studied and compared with those of unfilled PS. The shear compliance were studied and evaluated. Where the values of J' at w = 0.06 radians/s are 1´10-4 and 5.3´10-5 Pa-1 for PS and PS composite, respectively At w = 0.1 radians/s the addition of the rubber alters the value of J'' from 1.6´10-4 to 8.4´10-5 Pa-1. That means the stability of PS is enhanced by the incorporation of the rubber
