The invention relates to an economical method of making a polymer having reduced VOCs and coating compositions containing such polymers. In one embodiment, the method of invention requires providing a reactant mixture (a), providing a solvent mixture (b) comprising a reactive component (c) which is substantially free of any heteroatoms and is not a crystalline solid at room temperature and comprises (i) from 12 to 72 carbon atoms, and (ii) at least two functional groups, and subjecting the reactant mixture (a) in the solvent mixture (b) to polymerization conditions sufficient to polymerize reactant mixture (a) to provide a mixture (d) of a polymer (a') in solvent mixture (b), wherein reactive component (c) under the polymerization conditions is substantially nonreactive: (1) with the components of reactive mixture (a), (2) in the polymerization of reactant mixture (a) and (3) with the polymer (a'). Coating compositions of the invention comprising polymers made by the disclosed method provide low VOCs without any reduction in application or performance properties.

L'invention concerne un procédé économique de fabrication d'un polymère à COV réduit, ainsi que des compositions de revêtement contenant de tels polymères : Selon un mode de mise en oeuvre, le procédé de l'invention consiste à préparer un mélange réactif (a) fournissant un mélange solvant (b) comprenant un composant réactif (c) sensiblement dépourvu de tout hétéroatome et ne formant pas un produit solide cristallisé à température ambiante, comprenant (i) de 12 à 72 atomes de carbone, et (ii) au moins deux groupes fonctionnels, et à soumettre le mélange réactif (a)dans ledit mélange solvant (b) à des conditions de polymérisation suffisantes pour polymériser le mélange réactif (a) de manière à obtenir un mélange (d) d'un polymère (a') dans le mélange solvant (b), le composant réactif (c) étant, dans les conditions de polymérisation, sensiblement non réactif : (1) avec les composants du mélange réactif (a), (2) dans la polymérisation du mélange réactif (a) et, (3) avec le polymère (a'). Les compositions de revêtement selon l'invention renfermant des polymères préparés suivant le procédé précité fournissent des COV ne subissant aucune diminution, ni dans leurs qualités, ni durant leur emploi.
