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 radical polymerization is performed in presence of a metal scavenger system comprising a metal scavenger and an acid. These polymer dispersions are designated as water-in-water (w/w) polymer dispersions.

Polymers are provided, in which a pendant photoinitiator moiety is linked to the polymer structure via an amide or a succinimide.

Provided is an acoustic coupler capable of achieving both low elastic modulus and high deformability required for ultrasound imaging. The acoustic coupler is disposed between a probe for transmitting ultrasound waves and a subject, the acoustic coupler comprising a hydrogel including a copolymer that contains water. The copolymer comprises a monofunctional monomer having one ethylenically unsaturated group and a polyfunctional monomer having two to six ethylenically unsaturated groups. The molar ratio of the monofunctional monomer to the polyfunctional monomer is more than 90 and less than or equal to 3500.

A method of forming a particle includes, in a disperse phase within an aqueous suspension, polymerizing a plurality of mer units of a hydrophilic monomer having a hydrophobic protection group, thereby forming a polymeric particle including a plurality of the hydrophobic protection groups. The method further includes converting the polymeric particle to a hydrophilic particle.

The present invention relates to a novel coloring material including a polyamide powder and/or a polyurethane powder and a water-soluble dye. The coloring material of the present invention allows a water-soluble dye to be used in anhydrous formulations. Thereby, the range of use of dyes may be widened, reflectance may be excellent, and fluorescence properties may be obtained. Accordingly, the present invention may broaden the spectrum of cosmetic coloring materials used in limited applications in the cosmetic field.
