Abstract: A novel Bola-type ionic liquid based silicone surfactant was prepared by the reaction of α,ω-bis(chloropropyl) polysiloxane and N-methylimidazole.The former was prepared with 1,3-bis(chloropropyl)tetramethyl-disiloxane and octamethylcyclotetrasiloxane as starting materials under the catalytic action of concentrate hydrochloric acid.Chemical structure of the product was characterized by 1HNMR,FTIR and DSC.Its critical micelle concentration (cmc) and surface tension at cmc (γcmc) was measured.The first cmc is 0.13 g/L.The second cmc is 7.92 g/L,and γcmc is 24.3 mN/m.

Key words: silicone surfactant, ionic liquids, Bola type, synthesis, surface activity
