摘要： The present invention relates to methods for providing modified cement compositions having increased slip resistance and/or a decreased setting time in comparison to cement compositions comprising from 1 to 10 weight percent redispersible polymer powder (RDP) and water soluble cellulose ether in a specific amount from 0.1 to 1.0 weight percent, based on the total dry weight of said composition. Also provided are dry mortars comprising cement, RDP, water soluble cellulose ether and one or more additives selected from gelatin, bentonite and combinations thereof for use in such methods, and cement-free mixtures comprising water soluble cellulose ether and one or more additives selected from gelatin, bentonite and combinations thereof which may be added to cement binder for use a for use in such methods.

摘要： 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.
