A METHOD FOR PREPARATION OF A STABLE POLYMER DISPERSION WITH COLLOIDAL SILICA PARTICLES |
摘要 |
A method of preparing a polymer dispersion comprising (i) contacting an aqueous dispersion of de-ionized acidic colloidal silica particles with a first mixture of monomers to form a combination; (ii) polymerizing such combination at an initial pH of from 2 to 5 to at least 90% in completion; and (iii) adding a second mixture of monomers at a rate substantially equal to the rate of consumption of such second mixture of monomers to continue and complete the polymerization. The present invention further provides a polymer dispersion made from the above method. |
