Beschreibung
Zusammenfassung:	The invention relates to polymer comprising structural units according to formula (I), R1-X-(C═O)-NH-R2-NH-(C═O)-O-POA-R3-(O-POA-R4)n wherein R1 represents an organic group terminated by a hydrocarbyl group having 6 to 50 carbon atoms, X represents O or N-R5, wherein R5 represents a hydrogen atom or a hydrocarbyl group having 1 to 30 carbon atoms, R2 represents a hydrocarbyl group comprising an aromatic group and having 6 to 40 carbon atoms, POA represents a polyoxyalkylene group, R3 represents an organic group having 2 to 40 carbon atoms, n is an integer from 1 to 6, R4 is independently selected from -(C═O)-NH-R2-NH-(C═O)-NH-R1, -R6, wherein R6 represents a hydrogen atom or an aliphatic or aromatic group having 1 to 24 carbon atoms, and wherein the polymer has an average of at least 1.8 end groups R1 per molecule, a number average molecular weight in the range of 2000 to 100000 Daltons, and a polydispersity in the range of 1.0 to 5.0, wherein the quotient of the polydispersity divided by (n+1) is less than 1.0.
