This method is arranged such that (a) water-absorbing resin particles are surface-treated by using a crossing agent so that surfaces of the particles are cross-linked, (b) an additive for giving a function to the particles is added to the particles, (c) and a step of mixing the particles and the additive is carried out in a step of performing particle-size regulating treatment for the particles which includes agglomerated particles.

  • Patent number: 8283413
    Abstract: The present invention is drawn to an aqueous emulsion composition. The composition includes an aqueous phase and a hydrophobic phase dispersed in the aqueous phase, which includes a plurality of hydrophobic monomers. The monomers are acid-functionalized and hydrophobic, with less than 10% solubility in water. In one aspect, the monomers can be aromatic. Such monomers can be polymerized with other monomers to form latex particulates. A latex can include latex particulates dispersed in an aqueous fluid medium. In one embodiment, latex particulates can include from about 0.1 wt % to about 25 wt % of polymerized hydrophobic acid-functionalized monomer, and at least one other polymerized film-forming monomer. The latex can be formulated as an ink-jet ink.

  • Patent number: 8273823
    Abstract: The invention is directed to a microemulsion polymerization comprising adding a polymerization catalyst precursor, such as a transition metal complex in the higher of two accessible oxidation states, an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion. Radically polymerizable monomers and a reducing agent may then be added to the emulsion. The reducing agent converts the catalyst precursor to a catalyst for polymerization of the first monomer from the initiator. In certain embodiments the organic solvent may comprise radically polymerizable monomers. The aqueous solution may comprise a surfactant.
