Morphology and Mechanical Properties of Compatibilized β Nucleated Polypropylene/Polystyrene Blends

Article Preview

Abstract:

The β nucleated polypropylene (PP), uncompatibilized β nucleated PP/polystyrene (PS) and compatibilized β nucleated PP/PS blends were prepared on a twinscrew extruder.and then,added into compatibilizers styrene-ethylene-propylene block copolymer (SEP) or twostyrene-ethylene-butylene-styrene block copolymers (SEBS) with different content of styrene.The morphology and mechanical properties of these composites were investigated.
