Recuperación de Hips mediante sebs: Caracterización reológica y mecánica

The effect of reprocessing two mixtures: recycled high impact polystyrene (HIPS) with polybutadiene (PB); and HIPS with styrene-ethylene-butylenestyrene (SEBS) have been studied in this article. Our results show that tensile strength increases, while the lengthening and viscosity decrease, as the number of reprocessing cycles increases. If we mix PB or SEBS with degraded HIPS, the mechanical properties of the virgin material are recovered and the rheological behavior maintains the viscosity values for the mixture with PB but these diminish notably for the mixture with SEBS.
