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: 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.

Abstract: A latex particle comprises an interior core and an outer shell. The core comprises an acrylic or vinyl polymer, and the shell comprises a water soluble alkyd polymer and at least one surfactant. Substantially all or all of the alkyd polymer is present in the shell of the latex particle and substantially none or none or the alkyd polymer is present in the core of the latex particle. Also described is a process for making the latex particle wherein the water soluble alkyd polymer is present as a co-surfactant during polymerization.
