摘要：The present invention relates to coatings whose dynamic contact angle hysteresis measured in water to DIN EN 14370 by means of a Wilhelmy balance is at most 15° and which can be produced from star-shaped prepolymer-nanoparticle complexes and/or star-shaped prepolymers crosslinkable with one another and with the surface of the substrate to be coated, where the star-shaped prepolymer-nanoparticle complexes and/or star-shaped prepolymers have, prior to their crosslinking, at least three hydrophilic polymer branches which are intrinsically soluble in water and which bear, at all of or at some of their free ends, silyl end groups R1 of the following general formula (I): R1 is -CRa2-
Si(ORb)r(Rc)3-r, where Ra is hydrogen or a linear or branched alkyl group having from 1 to 6 carbon atoms, ORb is a hydrolysable group, Rc is a linear or branched alkyl group having from 1 to 6 carbon atoms and r is a number from 1 to 3, and which, at any ends present which do not bear silyl end groups, bear reactive groups which are reactive towards themselves, towards the substrate to be coated, towards entities
optionally introduced into the coating and/or towards the silyl end groups. The present invention also relates to a process for production of these coatings, and to star-shaped prepolymers as used in the coatings. The invention also relates to the use of the star-shaped prepolymers as additives of various compositions for providing temporary or permanent antisoiling properties to surfaces.
