| abstract |
The present invention relates to a process for the manufacture of soluble copolymers, which contain hydroxyl groups, can be crosslinked with organic polyisocyanates and are based on mixtures of styrene, methyl methacrylate, hydroxyethyl methacrylate, acrylic acid and glycidyl esters of alpha -alkylalkanemonocarboxylic acids and/or alpha , alpha -dialkylalkanemonocarboxylic acids, by heating in inert organic solvents in the presence of polymerization initiators and optionally chain stoppers, simultaneous esterification and polymerization taking place. |
