Title
(EN) METHOD FOR MAKING AN ORGANO-SOLUBLE (METH)ACRYLIC RESIN COMPOSITION, AND USE OF SAME AS BINDING AGENT FOR ANTIFOULING MARINE PAINTS
(FR) PROCEDE DE FABRICATION D'UNE COMPOSITION ORGANOSOLUBLE DE RESINE (METH)ACRYLIQUE, ET UTILISATION DE CETTE COMPOSITION COMME LIANT DES PEINTURES MARINES ANTISALISSURES
Abstract
(EN)
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 theCOOH 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.
(FR)
Pour obtenir une composition organosoluble de résine (méth)acrylique, on effectue l'estérification des fonctions -COOH d'un polymère comportant des motifs dérivés de l'acide méthacrylique, en milieu solvant, par Ti(OR)4, R représentant l'un parmi éthyle, isopropyle, n-butyle, t-butyle, 2-éthylhexyle et t-amyle. Selon l'invention, on conduit l'estérification en présence d'au moins un acide monocarboxylique R'COOH, R' représentant un radical alkyle en C1-C18, linéaire, ramifié ou cyclique; aryle; alkaryle; ou aralkyle, en arrêtant l'estérificattion avant la formation d'un gel, lorsque l'on a additionné les fonctions -COOH de la résine et de R'COOH avec un rapport molaire Ti(OR)4/fonctions -COOH de la résine compris entre 1 et 3, et un rapport molaire R'COOH/Ti(OR)4 compris entre 1 et 6.
