Patent number: 11802173Abstract: The wet adhesion of a coating composition may be improved through the use of voided latex particles as opacifying agents which contain a hollow interior as well as an outer shell of a polymer containing functional groups such as amino, 1,3-diketo, urea or ureido. Other types of functional groups may be introduced to the outer shell polymer in order to vary other desired characteristics of the coating. The voided latex particles are non-film-forming.Type: GrantFiled: October 11, 2021Date of Patent: October 31, 2023Assignee: Arkema Inc.Inventors: Keith R. Olesen, Matthew F. Boudreaux, Lily Liu

Patent number: 11384216Abstract: 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.Type: GrantFiled: June 10, 2019Date of Patent: July 12, 2022Assignee: Arkema Inc.Inventors: Lily Liu, Wayne Devonport, Daniel Edward Stark, Sr., Matthew F. Boudreaux

Patent number: 10899918Abstract: 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.Type: GrantFiled: June 19, 2017Date of Patent: January 26, 2021Assignee: Arkema Inc.Inventors: Lily Liu, Wayne Devonport, Daniel E. Stark, Matthew F. Boudreaux

Publication number: 20210009816Abstract: 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.Type: ApplicationFiled: February 19, 2019Publication date: January 14, 2021Inventors: Lily Liu, Keith J.
