A　series　of　novel　itaconic　acid　based　asymmetrical　gemini　surfactants　containing　two　long　alkyl　chains,　two　selfsame　nonionic　groups　along　with　an　anionic　moieties　covalently　attached　by　an　itaconic　acid　spacer　group　(polyoxyethylene　laurinol　ether　sodium　sulfoitaconate:　PLSS-n)　have　been　synthesized　through　esterification　and　sulfonation　reaction　using　itaconic　anhydride　(IAn)　and　polyoxyethylene　alkyl　ethers.　The　chemical　structures　of　the　PLSS-n　homologs　were　confirmed　through　FT-IR,　1H　NMR　spectra　and　elemental　analysis　(EA).　And　their　physico-chemical　properties　in　aqueous　solutions　were　further　investigated.　The　PLSS-n　species　have　lower　equilibrium　surface　tension　(γCMC)　and　critical　micelle　concentration　(CMC),　lower　Krafft　points　(Tk),　good　wettability　and　foaming　properties.　The　γCMC　and　CMC　values　of　PLSS-n　are　decreased　with　the　increase　of　the　temperature.　The　PLSS-n　homologs　exhibit　high　surface　activities　even　at　lower　temperature.　The　PLSS-n　homologs　all　exhibit　smaller　values　of　areas　per　molecule　(Amin)　and　larger　values　of　maximum　excess　surface　concentration　(Γmax).　The　rheological　behaviors　of　the　PLSS-n　solutions　show　that　only　PLSS-3　shows　shear　thinning　feature　with　the　increasement　of　shear　rate.　The　average　diameters　of　the　PLSS-n　aggregations　were　studied　by　Dynamic　light　scattering　(DLS)　at　25　°C.　Cryogenic　transmission　electron　microscopy　(cryo-TEM)　results　of　the　PLSS-n　indicate　that　these　gemini　surfactants　can　form　various　micellar　behaviors,　which　are　affected　by　different　combined　factors.　The　Small　angle　X-ray　scattering　(SAXS)　measurements　provide　evidence　of　the　anisotropic　lamellar　structure.　©　2019
