Beschreibung
Zusammenfassung:	The present invention relates to the preparation of Omega-(dimethylisopropenylbenzylurethane) polyalkylene glycols with alpha-alkoxy or alpha-dihydroxy groups and to the use thereof as hydrolysis-stable macromonomers for the dispersion and crosslinking of polymers in which A is C2-C4-alkylene m is an integer from 5 to 900, and R is C1-C20-alkyl, C6-C18-aryl or a radical according to formula 2a, 2b, 2c, 3a, 3b or 3c which 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 C3- or C4-alkylene.
