In the last decade, a large number of research actions focused on immiscible blends filled with carbon nanotubes (CNTs) [2-4].CNT is considered as one promising anisotropic nanofillers which can improve the morphology and end-use properties of multi-phase blends [5], such as blends of poly(styrene-co-acrylonitrile)(SAN) and poly(2,6-dimethyl-1,4-phenylene ether) (PPE).PPE is characterized by a high heat distortion temperature, outstanding toughness and a flame-retardant behavior, but possesses a poor processability.SAN with good chemical resistance has been reported as a possible polymer to improve the processability of PPE through blending [6].However, the immiscibility of these two components leading to a weak interfacial adhesion restricts the application of the blends.In this work, functionalized multi-walled carbon nanotubes (MWCNT) with random copolymers of methyl methacrylate and styrene (P(MMA-co-S)) were filled into SAN/PPE 40/60 blends.The grafted polymers on MWCNT are expected not only to enhance the dispersibility of MWCNT, but also to act as a compatibilizer by controlling the location of MWCNT in the blends, since the neat P(MMA-co-S) possesses good compatibility in SAN/PPE blends [6,7].
