Abstract: The present invention provides additives for dry mix or tape joint compound compositions comprising one or more cellulose ether powders containing on its surface one or more hydrophobic alkali swellable emulsion polymer (HASE), preferably, one that is not crosslinked or which comprises, in copolymerized form, no multi-ethylenically unsaturated monomer, and, optionally, an inorganic basic filler. The present invention also provides methods to make the additive comprising kneading at from 50 to 120° C. a wet cellulose ether mixture containing from 50 to 80 wt. % of water with from 0.5 to 25 wt. %, based on total cellulose ether solids, of the hydrophobic alkali swellable emulsion polymer; if desired, adding an inorganic basic filler, and drying and grinding. The additive can be combined with 0.1 to 20 wt. %, based on total cellulose ether solids, of a dry polyacrylamide.
