  Water soluble polymethyl(undecylicacidyl)silane,synthesized by the hydrosilylation of 10-undecylenic acid with polymethylsilane catalyzed by 2,2-Azobisisbutyronitrile,demonstrates selective dispersibility toward metallic single-walled carbon nanotubes(SWNTs)produced by arc discharge method.After heating in air at a temperature of 673 K and treatment with concentrated hydrochloric acid,the arc-discharged SWNTs are ultrasonically dispersed in an aqueous solution of polymethyl(undecylicacidyl)silane.
