Patent ID: 8889814

Claim:
A process for producing a compound of formula 2, in which R 1 is H, methyl or ethyl, R 2 is C 1 - to C 4 -alkyl, A is a C 2 - to C 4 -alkylene group, m is a number from 1 to 400 n is 1, 2, 3, 4 or 5, comprising the steps of: producing an α-hydroxy-Ω-alkoxypolyalkylene glycol with a secondary hydroxyl end group by alkoxylation of R 2 —OH and subsequent propoxylation, replacing the secondary α-hydroxy group through an aminolysis by a primary amino group, and reacting the primary amino group without addition of an alkoxylation catalyst with 2 mol of alkylene oxide, to give the dihydroxyalkylamino group.
