Additives for application in construction chemistry are proposed comprising an organic and/or inorganic core component A) with rheology-enhancing properties and a shell component B) applied to the same by virtue of physical and/or chemical interactions which acts as a coating. Component A) should be a of water-soluble and/or water-swellable and/or water-absorbable compound of the non-cellulose type with viscosity-enhancing properties in the final application. The shell component B) should preferably be a film-forming polymer which is able to release component A) during the application in construction chemistry in a retarded manner such as for example polyvinyl alcohol, polyvinyl acetate and polyethylene glycol. Component B) can be composed of several layers and comprises at least one reactive layer.

The present invention is a method for producing a ceramic porous body with high porosity and continuous macropores, which comprises mixing a ceramic powder with an aqueous solution of a gelable water-soluble polymer to form a slurry, gelling for a while to fix the tissue structure, freezing it to produce ice crystals in the gel tissue and creating structures that become continuous pores, thawing the ice by controlled atmospheric substitution-type drying method with the resulting water being replaced without damaging the gel, and then sintering it to produce a ceramic porous body having various porosities, pore diameters and pore shapes, while conventionally cracks and contraction were likely to occur during drying when the solids concentration of the slurry is less than 20 vol %, with the method of the present invention it is possible to control these problems even at a solids concentration of 10 vol % or less, manufacture and provide a ceramic porous body with a porosity of 72% to 99% and a compression strength of 0.4 MPa or more. |

The external surface of a tubular body such as well casing is coated with a substance that, upon exposure to cement, is unstable and degrades. After installation in a subterranean well and subsequent cementation, the coating degrades and forms a gap between the external surface of the tubular body and the cement sheath. Forming the gap is useful for obtaining optimal stimulation during the hydraulic fracturing of unconventional shale-gas formations. |

A water redispersible polymer powder is produced by drying an aqueous mixture of a water insoluble film-forming polymer and a colloidal stabilizer which includes a chelating agent and at least one water soluble polymer. The amount of chelating agent is at least 0.1% by weight, based upon the weight of the water insoluble film-forming polymer, and the amount of the at least one water soluble polymer is at least 0.1% by weight, based upon the weight of the water insoluble film-forming polymer. Dispersions or polymer compositions containing a chelating agent and water soluble polymer 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 colloidal stabilizer composition provides unexpectedly superior redispersibility for water insoluble film-forming polymers having very low carboxylation levels. |
