Abstract
Modification of the rheology of a liquid medium, aqueous or nonaqueous, with polymers in the form of specific particles obtained by grinding (micronizing) a porous macrogel, itself prepared by a process comprising a radical polymerization step which comprises reacting in the presence of pore formers monomers containing monomers bearing at least two ethylenic unsaturations, typically in combination with monomers bearing a single ethylenic unsaturation; a polymerization initiator; and optionally a polymerization control agent. These polymer particles keep other particles in suspension within the liquid medium, and also the stabilized suspensions are obtained.
