    摘要： A water redispersible polymer powder is produced by drying an aqueous mixture of a low carboxylation, low Tg, large average particle size water insoluble film-forming polymer latex or emulsion and a colloidal stabilizer. The latex polymer may have an average particle size of 2000 Å to 5,000 Å, and an amount of carboxylation of 0.1% to 2.75% by weight of at least one ethylenically unsaturated dicarboxylic acid, salts or mixtures thereof, based upon the weight of the polymer. Dispersions containing the polymer and a polyvinyl alcohol as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. Cement compositions such as mortars, which contain the redispersible polymer powder exhibit unexpectedly lower rates of viscosity buildup for better workability or troweling, faster set time, and superior heat flow characteristics.

    摘要： A water redispersible polymer powder may be produced by drying an aqueous mixture of a water insoluble film-forming polymer and a colloidal stabilizer comprising a chelating agent to obtain a water redispersible polymer powder, where the amount of chelating agent is at least 0.1% by weight, preferably at least 1% by weight, most preferably at least 3% by weight, based upon the weight of the water insoluble film-forming polymer. Dispersions or polymer compositions containing a chelating agent as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. The chelating agents are stable at high pH and so high pH spray dryable compositions containing them as a colloidal stabilizer may sit or be stored for prolonged periods of time prior to spray drying without loss of effectiveness of the colloidal stabilizer.

    摘要： An approach is provided for providing recommendations to a user based on user's role derived from the context information and an advanced user profile. A recommendation platform processes context information to determine one or more roles associated with a user. Next, the recommendation platform calculates at least one level of similarity between the one or more roles and one or more other roles associated with one or more other users. Then, the recommendation platform determines recommendation information associated with the one or more other users based, at least in part, on the at least one level of similarity. Next, the recommendation platform processes the recommendation information to generate one or more recommendations for the user.
