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.
