SURFACTANTS FOR THE MODIFICATION OF CLAY, METHOD OF SYNTHESIS AND THE NANOCOMPOSITES PRODUCED

摘要

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: R₁: C_nH_2n+1 with n = 1-20; C_nH_2n-OH with n = 1-4; or C_nH_2n-SO₃H with n = 1-4; R₂: C_nH_2n+1 with n = 0-20; C_nH_2n-OH with n = 1-4; or C_nH_2n-SH with n = 1-4; R₃: C_nH_2n+1 with n = 1-20; C_nH_2n-OH with n = 1-4; or C_nH_2n-SO₃H with n = 1-4; R₅: H, Cl, CH₃, NO₂, CN, SO₃H, Br, NH₂ or CO₂H; R₆: H, Cl, CH₃, NO₂, CN, SO₃H, Br, NH₂ or CO₂H; R₇: H, Cl, CH₃, NO₂, CN, SO₃H, Br, NH₂ or CO₂H; R₈: H, Cl, CH₃, NO₂, CN, SO₃H, Br, NH₂ or CO₂H; and X^-: Cl^-, Br^-, I^-, CH₃SO₄^-, C₆H₅SO₃^-, or CH₃COC^-.
