    摘要： A method of preparing an organic sol of particles is provided. Steps include: a) providing a suspension of particles in an aqueous medium; b) adding an organic liquid to form an admixture where the concentration of particles in the admixture is less than or equal to 40 percent by weight; c) maintaining the admixture at a temperature and pressure and for a time sufficient to reduce the water content to less than 30 percent by weight while simultaneously adding a water-compatible organic liquid at a rate sufficient to maintain a concentration of particles in the admixture at less than or equal to 50 percent by weight; and d) adding at least one polymer while maintaining the admixture at a temperature and pressure and for a time sufficient to provide an organic sol of particles comprising 1 percent by weight or less of water.
