Comparative study of PP-MA and PP-GMA as compatibilizing agents on polypropylene/nylon 6 blends

Polypropylene (PP) functionalized with maleic anhydride (PP-MA) has been used as compatibilizer for PP/nylon blends. PP functionalized with glycidyl methacrylate (PP-GMA) should be a good alternative dud to the reactivity of the epoxy group with -NH2 and -COOH groups. Blends of PP/PP-MA/nylon 6 or PP-GMA/nylon 6 were prepared using 30% of nylon (Ny6). The effect of the compatibilizers was evaluated by DSC, SEM micrograph and by mechanical properties. The analysis indicated that PP modified with MA showed the best compatibilizing effect in these systems. (C) 2001 Elsevier Science Ltd. All rights reserved.
