Abstract
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.
