Abstract: The application describes LCST polymers containing terminal and/or pendant alkoxysilane groups —Si(OR1)xR1y on the main chain, where R1 stands for an alkyl radical having 1 to 6 carbon atoms, y can adopt the values 0, 1 and 2, and furthermore: x+y=3. The LCST polymers can be crosslinked via a condensation reaction of the alkoxysilane groups. This enables the production from the LCST polymers of coatings which adhere very strongly to surfaces. Coatings of this type are not contaminated by free-radical initiators, meaning that premature curing cannot be initiated on incorporation, for example, into powder coatings. The application furthermore describes processes for the preparation thereof and the use thereof for coating particles and non-particulate substrate surfaces.

Abstract: The invention relates to a polymer of the formula (I) where R1 to R9 and the indices A, B, C, M, and N have the definitions stated in claim 1. The polymer of the invention is suitable in particular as a dispersant for pigments or fillers in paints.
