Polyurethanes which have olefinic double bonds and a content by mass of ethylene oxide units, incorporated via polyethylene glycol, of from 20 to 80% and which are obtainable by reacting (a) at least one organic polyisocyanate with (b) at least one polybutadiene derivative which is reactive toward isocyanates, and (c) if desired, one or more diols which contain, in addition, at least one further hydroxyl group or carboxyl group, and (d) a polyoxyalkylene glycol component having a molar mass of from 500 to 10,000 g/mol, wherein the ratio of NCO to OH equivalents, based on all the starting components (a) to (d), is from 0.5:1 to 1.2:1. The polyurethanes are useful, for example, as reactive emulsifiers.

Reactive emulsifiers based on unsaturated polyurethanes

Polyesters obtained by reacting from 5 to 50 parts of at least one linear or branched, aliphatic or cycloaliphatic, at least dihydric alcohol, from 2 to 40 parts of at least one at least dibasic, aromatic carboxylic acid, from 0 to 40 parts of at least one 2-alkenyldicarboxylic anhydride, from 10 to 30 parts of at least one at least dibasic, linear or branched, aliphatic carboxylic acid, from 0 to 15 parts of an aliphatic, linear or branched hydroxy acid, from 0 to 15 parts of an aliphatic, linear or branched polyamine having at least one primary and at least one secondary or tertiary amino group, from 0 to 15 parts of a glycidyl ester of a branched, aliphatic monocarboxylic acid or of a glycidyl ether of a branched, aliphatic alcohol, and from 0 to 15 parts of polyhydroxyamine are useful, for example, as additives in coating compositions.
