  • Patent number: 6534567
    Abstract: The invention concerns a method for making an organo-soluble (meth)acrylic resin composition which consists in: esterifying the COOH functions of a polymer comprising units derived from methacrylic acid, in a solvent medium, with Ti(OR)4, R representing one among ethyl, isopropyl, n-butyl, t-butyl, 2-ethylhexyl and t-amyl. The invention is characterised in that the esterification is carried out in the presence of at least a R′COOH monocarboxylic acid, R′ representing a linear, branched or cyclic C1-C18 alkyl radical; aryl; alkaryl; or aralkyl, by stopping esterification before a gel is formed, when the COOH resin and R′COOH functions have been added with a molar ratio Ti(OR)4/—COOH functions of the resin ranges between 1 and 3, and a molar ratio R′COOH/Ti(OR)4 ranges between 1 and 6.
