Recycling of plastics is very much hindered due to the process of segregation and sorting of individual polymer and also lack of compatibility between the different polymers. There is no single compatibilizer which can be effective for different pairs of polymer. If one could develop a multifunctional compatibilizer (MFC) that can be effective for a various range of polymers, the mixed plastics waste can be processed as such with minimal sorting/segregation. There are a number of reports on compatibilizer for specific pairs of polymer blends but there are practically no reports on single compatibilizer which works for different pairs of polymers. In the present studies, we have investigated the possibility of introducing different functional groups on a single polymer chain by chemical grafting. This multifunctional polymer has been used as compatibilizer for polypropylene blend with polymethyl methacrylate (PMMA) and ethylene vinyl acetate (EVA). © 2018, Springer Nature Singapore Pte Ltd.
