Abstract
Methods for manufacturing a polymer dispersion, polymer dispersions, and their use are provided herein. The methods of manufacturing the polymer dispersion comprise the steps of providing a reaction mixture in an aqueous medium comprising a polymeric dispersant and a monomer composition comprising radically polymerizable monomers, and subjecting the monomer composition in the reaction mixture to a radical polymerization to synthesize a dispersed polymer so as to form the polymer dispersion, wherein the ratio of the polymeric dispersant to the dispersed polymer in the polymer dispersion is in a specified narrow range. These polymer dispersions are designated as water-in-water (w/w) polymer dispersions.

A method for manufacturing a polymer dispersion comprising the steps of:
- A) providing a reaction mixture in an aqueous medium comprising
- a) a polymeric dispersant and
- b) a monomer composition comprising radically polymerizable monomers, wherein the radically polymerizable monomers are selected from the group of one or more of a non-ionic ethylenically unsaturated monomer, a cationic ethylenically unsaturated monomer, or an amphiphilic ethylenically unsaturated monomer;
- B) subjecting the monomer composition in the reaction mixture to a radical polymerization to synthesize a dispersed polymer and to form the polymer dispersion,
- wherein the ratio of the polymeric dispersant to the dispersed polymer in the polymer dispersion is in the range of 0.74:1 to 0.98:1.
A polymer dispersion comprising
- c) a polymeric dispersant and
- d) dispersed polymer derived from a monomer composition comprising radically polymerizable monomers, wherein the radically polymerizable monomers are selected from the group of one or more of a non-ionic ethylenically unsaturated monomer, a cationic ethylenically unsaturated monomer, or an amphiphilic ethylenically unsaturated monomer;
- wherein the ratio of the polymeric dispersant to the dispersed polymer in the polymer dispersion is in the range of 0.74:1 to 0.98:1.
