Beschreibung
Zusammenfassung:	omega -(dimethylisopropenylbenzylurethane) polyalkylene glycol is new. omega -(dimethylisopropenylbenzylurethane) polyalkylene glycol of formula (1), (4) or (5) is new. A : 2-4C alkylene; m : 5-900; R : 1-20C alkyl, 6-l8C aryl or radical of formula (2a), (2b), (2c), (3a), (3b) or (3c), which is bonded to the terminal oxygen atom of alkoxy group (A-O) in (1) via the valence denoted by *, and in which A is not exclusively 3-4C alkylene. An independent claim is also included for an aqueous dispersion preparable by the free-radical polymerization of an olefinically unsaturated compound in the presence of compound (1), (4) or (5) by mixing the olefinically unsaturated compound in water with the compound (1), (4) or (5), and triggering the polymerization by adding a free-radical initiator.
