A　comparative　study　of　the　viscoelastic　properties　of　the　wormlike　micellar　solutions　of　hexanediyl-alpha,omega-bis(dimethylcetylammonium　bromide),　referred　to　as　16-6-16,　and　cetyltrimethylammonium　bromide　(CTAB)　in　the　presence　of　sodium　salicylate　(NaSal)　has　been　carried　out.　In　terms　of　Cates　model　on　Maxwell　fluid,　the　characteristic　parameters　of　both　wormlike　micelles　were　revealed　and　compared.　The　results　were　discussed　on　the　basis　of　their　different　molecular　structures,　which　leaded　to　different　response　of　16-6-16　and　CTAB　to　salt.　(C)　2010　Elsevier　B.V.　All　rights　reserved.
