　　Polymer/carbon nanotube(CNT) composites have attracted considerable attention because of their unique physical properties[1～ 3].Recently,the CNT are used to reinforce the ceramic and metal composites due to its high length-to-diameter ratio,strength,elastic modulus,flexibility and unique conductivity along with other properties[4～ 6].Xie Xiaolin and his co-workers[7] found that maleic anhydride grafted styrene-(ethylene-co-butylene)-styrene copolymer(MA-SEBS) can effectively toughen the PP-matrix composites.
　　In the present work,MA-SEBS was used as compatibilizer for PP/CNT composite.The objective of the present investigation is to study the effect of MA-SEBS on properties of PP/CNT composites.To improve the dispersion,the PP powder,CNT and MA-SEBS were mixed for 24 h by ball mill machine,then,were blended with mixing chamber in the Brabender Plasticorder at 175 ℃ ,75 r/min for 10 min.The blends were compression molded into plaques at 175 ℃ .
