New polyamines or perfluoroalkyl polyamide, containing only one perfluoroalkyl group, are lipophobic and/or alcophobic surfactants useful as additives in foam extinguishers

The new polyamines or perfluoroalkyl polyamides, containing only one perfluoroalkyl group, are lipophobic and/or alcophobic, able to react with amines, polyamines, polypeptides resulting from the proteins and polysaccharides : New polyamines or perfluoroalkyl polyamides, containing only one perfluoroalkyl group, are lipophobic and/or alcophobic, able to react with amines, polyamines, polypeptides resulting from the proteins and polysaccharides, and are of formula RF-A-Z-B-E-V Xr. RF = linear or branched 4-20C perfluoroalkyl; A = -CH2CH2SO2-; B = O, [(CH2)m(N+>)gR2R3]n; E = nothing when B is O, [W{NR1(CH2)m}n(N+>)qR2R3]p when B is [(CH2)m(N+>)qR2R3]; a, b, c = 0-60 with a+b+c greater than 0; B = a variable going from 0 to 60 with a+b+c greater than 0; n = a whole number when q is 0, or 1 when Q is 1; m = 2 when q is 0, or 2 or 3 when q is 1; p = 1-10 when q is 1, or 0 to 10 when q is 0 q = 0 or 1; r = number of positive charges; R1 = H and/or -CH2COOM; R2, R3 = (H and/or -CHOOOM)/nothing when q is 0, lower alkyl groups when q is 1; W = -CH2CO- and/or -CH2C(OH)HCH2; V = -CH2COOM' when W is -CH2CO-, -CHC(OH)HCH2X' and/or glycidyl when W is CH2C(OH)HCH2-, H and/or - CHOOOM or -CHC(OH)HCH2X' and/or glycidyl when p is 0, U when B = O; U = H or -CH3; M = H, an alkaline ion; M' = H, alkaline ion, -CH3, -C2H5 when q = 0, - H, an alkaline ion, a negative charge, -CH3, -C2H5 when q = 1; X = nothing when q is 0, an halogen ion when q is 1; X' = halogen; Z = -NR1 when B is [(CH2)m(N+>)gR2R3]n, -NHCHUCH2(OCH2CHCH3)a-(OCH2CH2)b-(OCH2CHU)c when B is O. An independent claim is included for the preparation of the perfluoralkylated compounds by reacting an epihalohydrin or monohalogenated ester in the presence of di- or polyamine with a perfluoroalkylated or perfluoroalkenylated compound with an amine function of formula RF-A-NR1-[(CH2)m-NR2-]n-R3. RFlinear or branched 4-20C perfluoralkyl or perfluoroalkenyl; R1H or -CH2COOM; R2, R3lower alkyl groups, H or -CH2COOM; A : -CH2CH2SO2-; n : a whole number when R2 and R3 = H and 1, when R2, R3 = alkyl groups; m : 2 when R2, R3 = H, or 3 when R2, R3 = alkyl groups. La présente invention concerne la préparation de nouveaux polyamides ou polyamines perfluoroalkylés, possédant un groupement sulfonyle (SO2) non directement lié à la chaîne perfluorée, contenant un seul groupement perfluoroalkyle, ayant des propriétés lipophobes et/ou alcophobes et pouvant interagir ou réagir avec des amines, polyamines, polyéthoxyamines, polysaccharide
