Patent ID: 8318653

Claim:
A mixture comprising amphiphilic alkoxylated polyalkyleneimines comprising a polyalkyleneimine backbone comprising in condensed form repeating units represented by formulae (I), (II), (III) and (IV) wherein # in each case denotes a bond between a nitrogen atom and the free binding position of a group A 1 of two adjacent repeating units represented by formulae (I), (II), (III) or (IV); and wherein the variables in each case are defined as follows: A 1 is independently selected from the group consisting of linear and branched C 2 -C 6 -alkylene; E is independently at least one alkyleneoxy unit represented by formula (V) wherein * in each case denotes the bond to the nitrogen atom of the repeating units of formula (I), (II) or (IV); A 2 is in each case independently selected from the group consisting of 1,2-propylene, 1,2 butylene and 1,2 isobutylene; A 3 is 1,2-propylene; R is in each case independently selected from the group consisting of hydrogen and C 1 -C 4 -alkyl; m has an average value in the range of from 0 to 2; n has an average value in the range of from 20 to 50; and p has an average value in the range of from 10 to 50; the amphiphilic alkoxylated polyalkyleneimines comprising 1 repeating unit of formula (I), x repeating units represented by formula (II), y repeating units represented by formula (III) and y+1 repeating units represented by formula (IV), wherein x and y in each case have a value in the range of from 0 to 150; and the average molecular weight Mw of the polyalkyleneimine backbone in each case having a value in the range of from 60 to 10 000 g/mol; and mixtures of quaternization products thereof.
