Investigating the effect of Ma-grafted additives on PP and PA based compounds

The Mechanical performance of Polyamide6 and Polypropylene compounds in composition with maleic anhydride grafted additives has been investigated. The study allows direct comparison of the mechanical performance of different PA6 and PP based compounds and the effect of 5 different types of Ma-grafted additives. Furthermore, the comparison of these systems has been made over various content range of Ma-grafted additives. It is assumed that the efficiency of grafting maleic anhydride on polymer chains and the base polymer in these additives are two key points on improving the mechanical properties of above mentioned compounds. It was found that the Maleic Anhydride content in Ma-grafted thermoplastic copolymer additive is not playing an effective role on the performance of these additives as compatibilizer, Impact modifier and coupling agent...
