ABSTRACT:
Amphiphilic water-soluble alkoxylated polyalkylenimines of the general formula Iin which the variables are each defined as follows:R are identical or different, linear or branched C2-C6-alkylene radicals;B is a branch;E is an alkylenoxy unit of the formulaR1is 1,2-propylene, 1,2-butylene and/or 1,2-isobutylene;R2is ethylene;R3is 1,2-propylene;R4are identical or different radicals: hydrogen; C1-C4-alkyl;x, y, z are each from 2 to 150, where the sum of x+y+z means a number of alkylenimine units which corresponds to an average molecular weight Mwof the polyalkylenimine before the alkoxylation of from 300 to 10 000;m is a rational number from 0 to 2;n is a rational number from 6 to 18;p is a rational number from 3 to 12, where 0.8≦n/p≦1.0(x+y+z)1/2;and quaternization products thereof.
