In order to replace the role of maleated [styrene-block-(ethylene-co-butylene)-block-styrene](SEBS-g-MA) triblock copolymer by the recycled poly(vinyl butyral)(PVB) film as a toughening agent or an impact modifier, the influence of scrap PVB film on the phase morphology and mechanical properties of the binary nylon 6/SEBS-g-MA blends has been investigated. In Nylon 6 with 20 wt% PVB film, the PVB particles are dispersed in the Nylon 6 matrix as spherical particles of which the size is approximately 1.5 ㎛ in diameter. For the tertiary Nylon 6/SEBS-g-MA/PVB blends, under the fixed content of SEBS-g-MA or PVB at the most 20 wt%, the dispersed Particles increased with the PVB content. In particular, 12.5 wt% PVB influences the particle size and the phase morphology of the tertiary blends. Although the tertiary blends have lower impact strength than the binary Nylon 6/SEBS-g-MA blends, the impact strength is still much higher than that of Nylon 6 homopolymer. Thus, recycled PVB film is economically useful as a toughening agent or an impact modifier by partially replacing the role of SEBS-g-MA in Nylon 6 matrix.
