Embodiments of the present disclosure include organic polymeric particles, paper coating compositions, coated paper, and methods of forming coated paper with the paper coating compositions. The embodiments of the organic polymeric particle include an organic hydrophilic polymer with a unit for hydrogen bonding, and a hollow porous structure that comprises an organic polymer that at least partially surrounds the organic hydrophilic polymer, where the hollow porous structure has a pore surface area greater than 1 percent of a total theoretical exterior surface area of the hollow porous structure and the organic hydrophilic polymer and the hollow porous structure give the organic polymeric particle a void volume fraction of 40 percent to 85 percent.

Organic polymeric particles, paper coating compositions, and methods

A method of forming an organic polymeric particle, comprising (i) forming a core of an organic hydrophilic polymer with monomers that contains an acid group, a latent acid group, or a combination thereof; (ii) forming a shell that comprises an organic polymer with monomers that contains an acid group, a latent acid group, or a combination thereof to encapsulate the core, where the shell has an initial size; expanding the core to form a hollow porous structure from the shell, where the hollow porous structure has an expanded size larger than an initial size of the shell; and (iii) hydrolyzing the acid group, the latent acid group or the combination thereof of the hollow porous structure and the organic hydrophilic polymer to give the organic polymeric particle a void volume fraction of 40 percent to 85 percent.

Organic polymeric particles, paper coating compositions and methods

A process comprising heating an aqueous dispersion of first structured polymer particles at a temperature of at least about 155&#xb0; C., optionally in the presence of a base and/or a swelling agent, to produce an aqueous dispersion of heat treated structured polymer particles.

Process of heat treating structured polymer particles

Embodiments of the present disclosure include paper coating compositions, coated paper and/or paperboard, and methods of forming coated paper and/or paperboard with the paper coating compositions. The embodiments of the paper coating compositions contain high levels of hollow polymeric pigment relative to other pigments used in the paper coating composition (e.g., inorganic pigments). The paper coating compositions can provide the coated paper and/or paperboard with a wide variety of desirable features (e.g., high gloss, good smoothness, improved stiffness), while minimizing compaction (i.e., permanent deformation) of the underlying base paper.

Paper coating compositions, coated papers, and methods

Agglomerated hollow particle latex is employed as a filler in the wet end of the paper-making process to provide paper with improved properties.

Paper manufacturing using agglomerated hollow particle latex

The incorporation of oxazoline monomers into conventional latexes imparts resistance to flash rust and salt fog of industrial coatings which contain the oxazoline latex.

Latex containing oxazoline for industrial coatings

The present invention provides for a method of converting an anionic latex to a cationic latex by the addition of a steric stabilizer and a cationic surfactant. The invention also provides for a method of using the cationic latex prepared by the conversion, in an asphalt emulsion. The converted latex provides improved torsional recovery properties to the cured asphalt emulsion.

Latex conversion to cationic form use, for example in cationic asphalt

An adhesive of starch and an ammonium-based latex improves wet-pin adhesion for paperboard and corrugated board. The latexes are typical styrene-butadiene and carboxylated styrene-butadiene latexes but untypically are polymerized in the presence of a volatile base such as ammonium hydroxide.

Latex based adhesive composition for paperboard and corrugated board

A paper product, especially light weight papers, is prepared with a structured latex particle having opacity and reinforcing characteristics comprising a core region having a light scattering characteristic and T.sub.g of about 80 degrees C or higher and a shell region of about 25 degrees C or lower. The structured latex particle provides opacity to the paper without adversely affecting its mechanical strength.
