  • Patent number: 11161986
    Abstract: The present invention relates to a process comprising the step of contacting an aqueous dispersion of swelled polymer particles with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L. The swelled polymer particles arise from neutralization of alkali swellable polymer particles having a high acid core content and a low Tg shell. The composition arising from the process of the present invention is useful for improving open time, especially for low VOC coatings applications.
    Type: Grant
    Filed: February 26, 2018
    Date of Patent: November 2, 2021
    Assignees: Rohm and Haas Company, Dow Global Technologies, LLC

  • Publication number: 20200102412
    Abstract: The present invention relates to an aqueous dispersion of neutralized multistage polymer particles comprising an alkali metal base or a high boiling point amine salt of a carboxylic acid functionalized first stage, and a low Tg second stage (shell). The dispersion is useful as an open time additive.
