Abstract:
The invention relates to a copolymer which can be obtained by free-radical copolymerization of one or more urethane-based, polysiloxane-containing macromonomers and one or more further free-radically polymerizable comonomers. Processes for preparing the copolymer and its use as additive in coating compositions and plastics and as wetting agent and dispersant in homogeneous dispersions are also described.
