Crosslinked oxyalkylated polyalkylenepolyamines
First Claim
1. A crosslinked oxyalkylated polyalkylenpolyamine which is obtained by reacting a polyalkylenepolyamine, which is completely oxyalkylated at the nitrogen atoms, in each case by from 10 to 300 groups, and possesses from 50 to 2,000 repeating alkyleneimine units in the molecule, with from 0.5 to 10% by weight, based on the oxyalkylated polyalkylenepolyamine, of a crosslinking compound which possesses two or more functional groups which are capable of reacting with the terminal alcohol groups of the oxyalkylated polyalkylenepolyamine.
