Abstract

The invention relates to a polymer having a) a polymer backbone and b) one or more polymeric side chains covalently linked to the polymer backbone, wherein the polymeric side chains comprise a polyether segment and a polysiloxane segment, said polysiloxane segment having a number average molecular weight in the range of 1050 to 6000, and said polyether segment being positioned between the polymer backbone and the polysiloxane segment.
