Abstract
Non-aqueous dispersions of polymeric microparticles are disclosed. The dispersions are prepared by free radical initiated addition polymerization of a polymerizable monomer in the presence of a dispersion stabilizer in an organic liquid. The dispersion stabilizer is a styrene polymer terminated with an alpha, beta-ethylenically unsaturated group. The polymeric microparticles are useful as rheology modifiers in coating compositions.
