Zusammenfassung:The invention relates to a process for preparing an organic solvent-based dispersion comprising a melt-blended network of an epoxy-functional and/or amino-functional polymer having a polymer-O-Si-0-polymer linkage and a polyolefin (co)polymer having carboxylic acid and/or carboxylic acid anhydride groups, the process comprising the steps of a) forming the melt-blended network from a prepolymer, a silane-functional compound and the polyolefin (co)polymer in the absence of a solvent, b) mixing the melt-blended network with an organic solvent to make the organic solvent-based dispersion, and c) cooling the organic solvent-based dispersion. The invention further relates to a coating composition and to a coated metal substrate.
