Abstract
Crosslinked oxyalkylated polyalkylenepolyamines which can be obtained by reacting polyalkylenepolyamines, which are completely oxyalkylated at the nitrogen atoms, in each case by from 10 to 300 groups, and possess from 50 to 2,000 repeating alkyleneimine units in the molecule, with from 0.5 to 10% by weight, based on the oxyalkylated polyalkylenepolyamines, of a crosslinking compound which possesses two or more functional groups which are capable of reacting with the terminal alcohol groups of the oxyalkylated polyalkylenepolyamines, and a process for breaking water-in-oil emulsions.
