| 摘要 |
The invention relates to amphiphilic water-soluble alkoxylated polyalkylenimines of general formula (I), where the variables have the following meanings: R independently = linear or branched C2-C6 alkylenes, B = a branching, E = an alkylenoxy of formula (II), R1 = 1,2-propylene, 1, 2-butylene and/or 1, 2-isobutylene, R2 = ethylene, R3 = 1,2-propylene, R4 independently = H, C1-C4 alkyl, x, y, z each = 2 to 150, where the sum x+y+z indicates a number of alkylenimine units, the mean molecular weight Mw of the polyalkylenimine before alkoxylation is 300 to 10,000, m = a whole number from 0 to 2, n = a whole number from 6 to 18, p = a whole number from 3 to 12, where 0.8 =n/p =1.0 (x+y+z)1/2 and the quaternisation products thereof.
