    Abstract: Disclosed are voided latex particles, useful as opacifying agents for coating compositions containing organic solvents. The particles have a hollow interior, which substantially maintains its integrity after the particles are placed in contact with an organic solvent at 25°C for 30 days. The particles also have a hydrophilic polymeric interior shell surrounding the hollow interior that is swellable with an aqueous swelling solution. The particles have first and second polymeric intermediate shells, surrounding the interior shell, formed from polymers that are different from each other and different from the interior shell polymer. Finally, the particles have an outer polymeric shell, surrounding the interior shells, which is formed from up to 100% by weight, as polymerized units, of methyl methacrylate. The interior shells and the outer shell each have a Tg greater than 60°C. Also disclosed is a multi-stage emulsion process for making the particles.

    Abstract: A process for forming voided latex particles is improved by combining swelling and polymerization of an outer shell into a single step. The process includes contacting multi-stage emulsion polymer particles comprising a core, at least one intermediate shell, with a swelling agent, and polymerizing an outer shell after said contacting with swelling agent wherein the core and the at least one intermediate shell are contacted with swelling agent in the presence of less than 0.5% monomer based on the weight of the multi-stage emulsion polymer particles, and substantially all of the swelling occurs during polymerization of the outer shell.

    Abstract: Latex emulsions and a process of making the same that incorporates voided latex particles having a core with a hydrophilic component; at least one intermediate shell with, as polymerized units, one or more hydrophilic monoethylenically unsaturated monomer, one or more nonionic monoethylenically unsaturated monomer, or mixtures thereof; an outer shell formed of a polymer having a Tg of at least 60? C; and a surface treatment applied to the outer shell in which a plurality of silicone oligomers with reactive functional groups are cross-linked with one another in order to provide a cross-linked outer surface. The core and the at least one intermediate shell are contacted with a swelling agent in the presence of less than 0.5% monomer based on the overall weight of the voided latex particles. In addition, one or more of the core, the intermediate shell, or the outer shell includes a surfactant.

    Abstract: A method of forming latex composite polymer particles produces hydrolysis resistant, composite polymer particles that can be used in aqueous latex compositions. Each of the latex composite polymer particles includes a first phase comprising a vinyl ester oligomer or polymer; optionally, an intermediate phase; and at least one second phase comprising an acrylic oligomer or polymer, a styrene oligomer or polymer, an acrylic-styrene copolymer, or mixtures thereof. The second phase and/or the intermediate phase at least partially encapsulates the first phase. The intermediate and second phases are more hydrophobic than the first phase. Optionally, the first phase, the second phase, and/or the intermediate phase may further comprise a cross-linking agent.
