ABSTRACT:
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 C2-C8; 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.
