Abstract
The invention relates to a process for preparing polymers for coating applications by polymerizing esters of acrylic acid or of methacrylic acid or vinyl aromatics or other free-radically polymerizable vinyl compounds or monomer mixtures composed predominantly of such monomers by means of a continuous polymerization process. In particular, the invention relates to a solvent-free preparation process for polymers, through which the binder can be prepared for coating applications with superior processing properties, very good thermal stability, improved pigment wetting and a higher gloss.
