Abstract

Post-consumer polypropylene (PP) has been toughened via a novel Solid-State Shear Pulverization (S3P) process (which employs a modified twin-screw extruder made by Berstorff Maschinenbau, GmbH, Germany) and with the addition of a small amount of polyolefin plastomer (POP). It is the use of this novel process, in combination with the incorporation of small amounts (approx. 5% by weight) of POP that creates the desired material. Notched impact strength of recycled PP/POP blends increased by 40% as compared with that of recycled PP alone: fracture toughness values improved similarly. The S3P process is proposed to function by causing mechanochemical mechanisms that lead to self-compatibilization between the rubber modifier and the polypropylene base material.
