New hydrophobic/lipophobic perfluoroalkylated polyamide surfactants containing a polymeric hydrophilic group, useful in extinguishing foams

摘要

Hydrophobic or lipophobic perfluoroalkylated polyamide surfactant (I) containing a polymeric hydrophilic group, is new. Hydrophobic or lipophobic perfluoroalkylated surfactant (I) of formula A-B1-(D-Rf)r containing a polymeric hydrophilic group, is new. RfCnF2n+1; n : 4-20; A : X-E-CO-[NH-(CH2)m-N+>(R1)(R2)-CH2-CO]p-NH-(CH2)m-N+>(R1)(R2)- or ->OOC-CH2-[N+>(R1)(R2)-(CH2)m-N+>(R1)(R2)-(CH2)m-NHCO-CH2]p-N+>(R1)(R2)-(CH2)m-NH-; B1-CH2CH(OH)CH2OC2H4-, -CH2CH(OH)CH2(OC2H4)1-3SC2H4-, -CH2CH(OH)-CH2SC2H4-, -CH2CH(OH)-, -CH2CH(OH)-CH2-CH=CH-, -CH2CH(OH)-CH2-O-C3H6S-C2H4- or -CH2CH(OH)CH2-N=; E : absent, -(CH2)q-, 1,2-cyclohexadiyl, 1,2-benzen-diyl, 2,3-pyridin diyl or pyrazin-2,3-diyl; M+>alkaline ion or absent; m, p, q : 2-3; and R1, R2lower alkyl groups. Provided B1 is -CH2CH(OH)CH2OCH2CH(I)CH2- or -CH2CH(OH)CH2OCH2CH=CH-, when A is ->OOC-CH2-[N+>(R1)(R2)-(CH2)m-N+>(R1)(R2)-(CH2)m-NHCO-CH2]p-N+>(R1)(R2)-(CH2)m-NH-. Provided that D is -CH2CH(I)CH2 and/or -CH2CH=CH-, when B1 is -CH2CH(OH)-CH2-N= and absent in other cases. Provided that r is equal to 2 when B1 is -CH2CH(OH)CH2-N= and 1 in the other cases. Provided that X is alkyl or aryl, when E is absent and ->OOC- when E is present. An independent claim is included for the preparation of (I).
