Dispersed polymers comprising microparticles stabilized with two kinds of steric stabilizers are disclosed. The first stabilizer is an essentially linear polymer having a terminal end attached to the microparticle. The second stabilizer is a graft or comb polymer comprising an acrylic backbone having side chains. This stabilizer, in contrast to the first stabilizer, may be attached to the core by means of a plurality of functional groups placed along the backbone of the graft polymer.
On divulgue des polymères dispersés comprenant des microparticules stabilisées avec deux types de stabilisants stériques. Le premier stabilisant est un polymère essentiellement linéaire dont une extrémité est attachée à la microparticule. Le second stabilisant est un polymère greffé ou en peigne comprenant un squelette acrylique portant des chaînes latérales. Ce stabilisant, contrairement au premier stabilisant, peut être attaché à la partie principale au moyen d'une pluralité de groupes fonctionnels placés le long du squelette du polymère greffé.
