摘要: Ternary nanocomposites (NCs) were obtained by melt-mixing maleic anhydride-modified polypropylene (gPP) with previously prepared polyamide-12 (PA12)/organically modified montmorillonite (OMMT) NCs. During melt-mixing, OMMT migrated from the PA12 phase to gPP/PA12 interphase. Moreover, a critical concentration of was found saturate interphase and, at higher contents, excess gPP matrix. When compared unfilled blends, addition caused change in microstructure. The average size dispersed particles NCs be independent content. At contents below concentration, that is, when located interphase, Young's modulus remained practically unchanged and ductile nature ternary maintained. However, increased linearly became brittle, due presence POLYM. ENG. SCI., 2017. © 2017 Society Plastics Engineers
