Novel alco-oleophobic fluorinated surfactants, processes for preparing same and uses thereof

摘要

New water-sol. polyperfluoroalkylated tensides, derived from polymers with polycarboxylic function, are free from quat. organic N, have at least 2 perfluoroalkyl 4-20C gps. linked indirectly to the COOH functions of the polymer through an ester or amide bond (where the N must carry a hydrophilic gp. to promote alcohol repellency), and have formula (I) where Y = -CH2CH(Z)-, or a simple bond; Q1 = -CONH(CH2(OH)CHCH2N(A-NHR2)m-B(CH2)x-RF, or -CONH(CH2(OH)CHCH2N(R2)AN(R2)m-B(CH2)x-RF, or -CONH(CH2(OH)CHCH2N(A-OH)m-B(CH2)x-RF when A = alkylene; -COOARFl -COOOANB(R2)(CH2)x-RF when Y = -CH2(Z)CH- and A = alkylene; or gps. (i) or (ii) when Y = -CH2CH2- Q2 = -CONH2 and -COOM, -COOWOR3, or -N(CH2C2H4SO3M when Y = -CH2(Z)CH-; RF = 4-20C perfluoroalkyl; R1 = -COOM when Y = -CH2(Z)CH- and H when Y is a simple bond; A = 2-6C alkylene or other divalent gp., e.g. -CH(U)CH2(OCH2(CH3)CH)a-(OcH2CH2)b-(OCH2(U)(CH)c-, -(cH2CH2NH)q-CH2CH2- when A is included between 2N atoms; R2 = -CH2COOM, H or 1-4C alkyl; R3 = Ph, alkylphenyl or alkyl; a, b, c = 0-60; n, p = more than 10; m, l = 1-20; q, x = 0-4; B = -SO2 or -CO qwhen x = 0-4, or a simple bond when x = 1-4; W = -(cH2CH2O)l-CH2CH2-; Z = Ph, -OCH3, H, Me, Et, -CONH2, -COOCH3, -CH2OOCCH3, or -N-pyrrolidone; U = H or Me; M = H, alkali metal or NH4.
