The present invention relates to the preparation of Ω-(dimethylisopropenylbenzylurethane) polyalkylene glycols with α-alkoxy or α-dihydroxy groups and to the use thereof as hydrolysis-stable macromonomers for the dispersion and crosslinking of polymers n n nin which, A is C 2 -C 4 -alkylene, m is an integer from 5 to 900, and R is C 1 -C 20 -alkyl, C 6 -C 18 -aryl or a radical according to formula 2a, 2b, 2c, 3a, 3b or 3c n n nwhich is bonded to the terminal oxygen atom of the alkoxy group (A-O) in formula 1 via the valence denoted by *, and in which A is not exclusively C 3 - or C 4 -alkylene. |
