    摘要: Water-insoluble polymers are prepared by free radical polymerization of ethylenically unsaturated monomers by a process in which the polymerization is carried out in an aqueous gel phase having a viscosity of at least 800 mPa.s and the gel former has a molecular weight of more than 20,000. The dispersions obtained have a long shelf life and the polymer can be readily precipitated.
