Process for preparing acid-modified aromatic hydrocarbon resins and their salts

The invention relates to a process for the preparation of aromatic hydrocarbon resins which have been modified by means of aromatic carboxylic acids, in which the aromatic carboxylic acids and methanesulphonic acid are suspended in an aliphatic solvent, and the aromatic, unsaturated hydrocarbons are...
