One-step compatibilization of polyamide 6/ poly (ethylene-1-octene) blends with maleic anhydride and peroxide

Polyamide 6/poly(ethylene-1-octene) (POE) blends were prepared in the presence of both maleic anhydride and peroxide via melt blending. The intrinsic viscosity, mechanical properties, rheology, and phase morphology of blends were evaluated. Molau test was adopted to confirm the formation of a graft copolymer between PA 6 and POE, rheology property also indicated the graft reaction. The SEM analysis showed a significant reduction in particle size of seperation phase after one-step compatibilization. It provides a promising method to obtain toughened polyamide material.
