A surfactant, a clay modified with a surfactant, the preparation processes described, and also the polymer nanocomposites produced from the modified clay. The surfactant of formula (I), characterized in that: R 1 : C n H 2n+1 with n = 1-20; C n H 2n -OH with n = 1-4; or C n H 2n -SO 3 H with n = 1-4; R 2 : C n H 2n+1 with n = 0-20; C n H 2n -OH with n = 1-4; or C n H 2n -SH with n = 1-4; R 3 : C n H 2n+1 with n = 1-20; C n H 2n -OH with n = 1-4; or C n H 2n -SO 3 H with n = 1-4; R 5 : H, Cl, CH 3 , NO 2 , CN, SO 3 H, Br, NH 2 or CO 2 H; R 6 : H, Cl, CH 3 , NO 2 , CN, SO 3 H, Br, NH 2 or CO 2 H; R 7 : H, Cl, CH 3 , NO 2 , CN, SO 3 H, Br, NH 2 or CO 2 H; R 8 : H, Cl, CH 3 , NO 2 , CN, SO 3 H, Br, NH 2 or CO 2 H; and X - : Cl - , Br - , I - , CH 3 SO 4 n - , C 6 H 5 SO 3 n - , or CH 3 COC - . |
