ABSTRACT:
Method of producing sterically stabilized polymer dispersions by polymerizing ethylenically unsaturated monomers in an aqueous phase (as a dispersion medium) in the presence of an initiator system and a water-soluble macromonomer which is an esterification product of maleic acid, fumaric acid, maleic anhydride, or mixture thereof and polyalkylene glycols and/or monoalkyl ether of polyalkylene glycol, having a degree of esterification between 50% and 100%. The dispersions obtained according to this method possess high electrolyte stability, shear stability, and frost stability, even without addition of conventional emulsifiers and emulsification adjuvants.
