Abstract:
An amphiphilic compound of the general formula I ##STR2##in which R.sup.1 and R.sup.3 are, independently of one another, a hydrogen or a hydrocarbon radical with 1 to 22 carbon atoms with the proviso that one occurrence of R.sup.1 is a hydrocarbon while the other is hydrogen, and one occurrence of R.sup.3 is a hydrocarbon while the other is hydrogen, R.sup.2 is a radical which contains 2 to 100 carbon atoms and 1 to 12 oxygen and/or nitrogen atoms and X and Y are, independently of one another, each selected from the group consisting of substituents of the formula:--(C.sub.2 H.sub.4 O).sub..alpha. (C.sub.3 H.sub.6 O).sub.62 Hwhere .alpha. is 0 to 50 and .beta. is 0 to 60 and .alpha.+.beta.=1 to 100, the formula:--(C.sub.2 H.sub.4 O).sub..gamma. (C.sub.3 H.sub.6 O).sub.67 --FRwhere .gamma. and .delta. each equals 0 to 20, .gamma.+.delta.=0 to 40 wherein FR is selected from the group consisting of --CH.sub.2 --COOM, --SO.sub.3 M, --P(O)(OH).sub.2, --C.sub.2 H.sub.4 SO.sub.3 M, and --O--C(O)--C.sub.2 H.sub.3 (SO.sub.3 M)--CO.sub.2 M"" where M and M"" are each alkali metal or ammonium or alkanolammonium or 1/2 alkaline earth metal, and the formula CH.sub.2 [CHO(C.sub.2 H.sub.4 O).sub..epsilon. (C.sub.3 H.sub.6 O).sub..eta. H].sub.z CH.sub.2 --O(C.sub.2 H.sub.4 O).sub..mu. (C.sub.3 H.sub.6 O).sub.92 --H where z is 3 to 6, .epsilon. and .mu. each equals 0 to 30, .eta. and .rho. each equals 0 to 30 and wherein any alkoxide units present are incorporated randomly or blockwise and the sequence is arbitrary.
