Abstract: The present invention provides dry mix compositions for use in making gypsum plasters or mortars comprising gypsum, preferably, phosphorous gypsum one or more retarder, and one or more crosslinked cellulose ethers containing polyether groups. The compositions enable the provision of gypsum dry mixes, such as those from phosphorus gypsum, that make gypsum mortars with less stickiness while reducing the amount of cellulose ether in the dry mix.

Abstract: The present invention provides cementitious tile adhesives comprising ordinary Portland cement, sand or another inorganic filler, and from 0.12 to 0.6 wt. % of total solids of one or more polyether group containing crosslinked cellulose ethers. The present invention also provides methods of making the polyether group containing crosslinked cellulose ethers comprising crosslinking a cellulose ether at 90° C. or less, in an inert atmosphere, e.g. nitrogen, in the presence of a polyether group containing crosslinking agent and in the presence of alkali; the process may comprise part of a stepwise addition process of making of a cellulose ether itself in which the crosslinking of the cellulose ethers precedes at least one addition of alkyl halide or alkylene oxide to form, respectively, alkyl or hydroxyalkyl groups on the cellulose.

Abstract: A mixture of a cellulose derivative and a liquid diluent is prepared which comprises at least 5 weight percent of the cellulose derivative, based on the total weight of the cellulose derivative and the liquid diluent. The mixing operating causes air to be entrapped in the mixture. The time for at least partially removing entrapped air is reduced by providing a cellulose derivative having a specific surface area of less than 0.20 m2/g measured by BET method for preparing the mixture.
