CA 2364553

The invention relates to cross-linked acrylic microparticles, a method for the production thereof by polymerization in a dispersion in a non aqueous medium and to the uses thereof in covering or moulding compositions involving a favourable compromise between hardness, flexibility and adhesion. The micropparticles are obtained from a composition comprising: 50-99 % mols of a constitutent (A) consisting of Cardura E 10 (meth)acrylate and optionally alkyl (meth)acrylate in C¿2?-C¿8?; a compound (B) consisting of at least one monomer or oligomer having at least 2 ethylenic unsaturations; a compound (C) consisting of at least one monomer or oligomer having in addition to one ethylenic unsaturation at least one second function (F1) with the possibility of at least partial chemical modification of the initial functions f1 into final functions f2.

L'invention concerne des microparticules acryliques réticulées, un procédé de préparation par polymérisation en dispersion en milieu non aqueux et des applications dans des compositions de revêtement ou de moulage avec un bon compromis dureté, flexibilité et d'adhérence. Ces microparticules sont obtenues d'une composition comprenant: 50 à 99 % en moles d'un composant A constitué de (méth)acrylate d'isobornyle et/ou de norbornyle et/ou de cyclohexyle et/ou (méth)acrylate de Cardura E10 et en option un alkyl (méth)acrylate en C2-C8; un composant B constitué d'au moins un monomère ou oligomère ayant au moins 2 insaturations éthyléniques; un composant C constitué d'au moins un monomère ou oligomère ayant en plus d'une insaturation éthylénique au moins une deuxième fonction f1 avec la possibilité de modification chimique au moins partielle des fonctions initiales f1 en fonctions finales f2.
