Abstract:
An aqueous polymer emulsion comprising water and swollen multi-stage polymer is provided. The swollen multi-stage polymer has low dry bulk density, as measured by centrifugation. To achieve the low dry bulk density, the polymer is highly swollen in such a way that it does not subsequently collapse. The polymer is useful in paint and paper coatings.
