Linear low-density polyethylene（ LLDPE） / polyamide 6（ PA6） / compatibilizer blends are interesting as
the model blends of recycled multilayer films. The aim of this study was to evaluate influences of compatibilizers
on morphology and mechanical properties of LLDPE / PA6 / compatibilizer blends. The used compatibilizers
have approximately the same content of polar maleic anhydride and different types of non-polar main
chain each other. The compatibilizers minimized the size of PA6 particles in the LLDPE and improved impact
strength significantly. Maleic anhydride grafted polystyrene-block-poly（ethylene-butene）-block-polystyrene
（SEBS） showed remarkable performance in regard to minimization of PA6 particle size and improvement of
the impact strength. Because the malic anhydride content was almost same among these compatibilizers, it
was estimated that chemical structure of main chain of the compatibilizer influenced PA6 particle size and impact
strength of the blends.
