Abstract

The compatibilizing effect of hyperbranched poly(amide-ester) grafted polypropylene (PP-HBP) had been investigated in polypropylene (PP)/poly(vinyl chloride) (PVC) BLENDs. In this work, PP/PVC/PP-HBP BLENDs were prepared by melt mixing. Mechanical and rheological properties and phase morphologies of the BLENDs were studied as a function of PP-HBP. The results showed that the tensile strength of the BLENDs reached the maximum value when the content of PP-HBP was 5 phr and then dropped on the increase of PP-HBP. The impact strength of the BLENDs showed a small change as that of pure PP/PVC BLEND, and the viscosity of the PP/PVC/PP-HBP BLENDs was higher than that of pure PP/PVC when the amount of PP-HBP added was£ 5 phr. The viscosity of the PP/PVC/PP-HBP BLENDs was lower than that of pure PP/PVC BLEND when PP/PVC BLEND contained PP-HBP > 5 phr. The scanning electron microscopy (SEM) showed that a two-phase morphology was characteristic of all BLENDs. In presence of PP-HBP, the PVC spherical droplets of the minor phase dispersed in a PP continuous matrix phase, whereas there was a large difference among the minor-phase particle sizes. The SEM photos also confirmed that PP-HBP could enhance the adhesion at the interface and reduce the phase separation of PP/PVC BLEND. The tensile strength of the BLENDs was in accordance with their morphology.
