| abstract |
The present invention relates to a polymer comprising: a) at least one segment of a polyether polyester copolymer, wherein the polyether polyester copolymer comprises a polymer selected from the group consisting of formula (II)—[CR 1 2 ] n -O- of ether units, wherein n is an integer from 2 to 4, R 1 independently of one another represents an organic group having 1 to 30 carbon atoms or hydrogen, and wherein in the case where n is equal to 2 at least one R 1 represents a group having the formula- ether groups of R 2 -O-R 3 , wherein R 2 and R 3 independently of one another represent an organic group having 1 to 30 carbon atoms, and b) are attached to the at least one polyether polyester copolymer chain at least one polysiloxane segment on the segment. |
