| titleOfInvention | Process for preparing polymer emulsions |
| abstract | A process for preparing emulsion polymer particles comprising: (a) providing an aqueous emulsion of a multi-stage emulsion polymer, comprising a core stage polymer and a shell stage polymer, wherein the core stage polymer comprises, as polymerized units, from 5 to 100 percent by weight, based on the weight of the core stage polymer, of hydrophilic monoethylenically unsaturated monomer, and from 0 to 95 percent by weight, based on the weight of the core stage polymer, of at least one nonionic monoethylenically unsaturated monomer; and wherein the shell stage polymer comprises, as polymerized units, at least 50 percent by weight of nonionic monoethylenically unsaturated monomer; (b) adding an effective amount of one or more polymerization inhibitors or reducing agents to substantially stop any polymerization; (c) providing monomer at a level of at least 0.5 percent by weight based on the weight of the multi-stage emulsion polymer; (d) adding swelling agent; and (e) reducing the level of monomer by at least fifty percent. |
