The results of FTIR spectra and transmission electron microscopy (TEM) Received in revised form showed that ammonium polyphosphate (APP) and clay were exclusively dispersed in the PA6 phase. Clay 10 January 2015 modified with poly (styrene-co-maleic anhydride) (SMA) was selective localization at the interface of Accepted 26 January 2015 blends. Introduction of clay and modified clay to blends caused the dispersion of clay not only in PA6 Available online 3 February 2015 phase, but also at the interface. The flame retardancy was evaluated by limiting oxygen index (LOI), vertical flammability test, and cone calorimeter tests. For the blends with dispersed
