Abstract: Light-stabilized star polymer microparticles are described which are prepared with particular advantage by group transfer polymerization. The light stabilization is effected by carrying out at least a part step of the polymerization in the presence of a light stabilizer, for example a hindered amine or/and a UV absorber. With particular advantage, those light stabilizers are used which contain reactive groups in the molecule and, in this way, can be chemically incorporated into the polymer. The polymer microparticles show excellent light stability and are outstandingly suitable as constituents in coating compositions which can be processed, for example, to give coating films of high light stability.

Abstract: The polymer microparticles, which contain at least one light stabiliser and free epoxide groups, are prepared by polymerising suitable monomers, at least one of these monomers being an epoxide which contains at least one further reactive group, and at least part of the polymerisation being carried out in the presence of at least one light stabiliser. The polymer microparticles can be used in coating compositions which contain a disperse phase containing these particles and a liquid continuous phase. … Coatings and paints based on the compositions according to the invention have increased weathering resistance, in particular high light stability.
