Method of making polymeric particles |
| abstract |
The present invention relates to a polymer comprising polymerized units of methacrylic acid and additional monomers having a total monomer composition by weight comprising polymerized units of 5 to 25% by weight of methacrylic acid and 75 to 95% by weight of additional monomers A process for producing sex particles by stepwise or gradient emulsion polymerization, wherein the further monomers are selected from C1- to C4-alkylesters of methacrylic acid and/or C1- to C4-alkylesters of acrylic acid, wherein further wherein the weight ratio of polymerized units of methacrylic acid to monomers increases in a gradient or stepwise manner from the center of the particle to the surface, and wherein the polymeric particles are obtained in the form of an aqueous dispersion. . |
