RHEOLOGICAL AND EXTRUDATE BEHAVIOR OF POLYPROPYLENE LATEX RECLAIM BLENDS/

The rheological and extrudate behaviour of polypropylene/latex reclaim blends were evaluated using a capillary rheometer. The study shows th at the viscosity of polypropylene increases with increasing latex recl aim content while the variation of viscosity is predominant only at lo wer shear stresses. The temperature sensitivity of the blends does not vary considerably with the addition of about 30 weight percent latex reclaim. The latex reclaim reduces the distortion of the extrudates of polypropylene/latex reclaim blends.
