<p>Cross-linked particles having a size ranging from 10-300 nm, obtained by polymerization in a dispersion in a non-aqueous, non-solvent medium of the formed polymer of a composition consisting of unsaturated ethylenically polymerizable compounds, comprising: at least one monomer (A), comprising one single ethylenicunsaturation, whereby the microparticles formed in said non-aqueous medium are autostablilized during and after polymerization without any other addition of a polymer having a stabilizing agent function either before, during or after polymerization; at least one compound (B) comprising at least two ethylenic unsaturations and, optionally according to the cases in question, at least one compound (C) comprising one single ethylenic unsaturation and/or at least one compound (D) which is different from A, B and C and comprising at least one ethylenic unsaturation that can be radically polymerized and at least one second reactive function (f1) that is different from an ethylenic unsaturation.</p> |
