Abstract
Melt blending of polypropylene (PP) and poly (ethylene terephthalate) (PET) was carried out in a single screw extruder. The extruded blend was continuously drawn using an on line stretching equipment at different stretch ratios. The stretched blend was injection moulded to obtain an in-situ composite where PET microfibrils are randomly distributed in an isotropic PP matrix. The morphology of the blend was studied at the different stages of the composite preparation at different stretch ratios. It was found that the fibril diameter decreased as the stretch ratio increases. The thermal characterization of the stretched blend indicated that the PET phase act as nucleating agent for the crystallization of PP.
