An investigation is reported here which aims to study the possibility of recycling waste polyurethane powder by melt blending with polypropylene. Improvement in the technological properties is found to be possible by increasing the miscibility of the blend by using a series of maleic-anhydride based compatibilizers. Mechanical properties were found to increase with increase in the compatibilizer content. It is claimed that the explanations given in this paper are unique in that through the use of a series of maleic anhydride based compatibilizers with PU/PP blends, it is possible to get materials with high mechanical properties which is corroborated by morphological and contact angle studies.
