Patent number: 8338508Abstract: A film that is both elastic and water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. To achieve these dual attributes, the film contains an olefinic elastomer and a water-soluble polymer. Although these polymers are normally chemically incompatible due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the polyolefin, water-soluble polymer, and other film components, the relative amount of the film components, and so forth. For example, certain water-soluble polymers may be selected that have a low molecular weight and viscosity to enhance their melt compatibility with nonpolar polyolefins. This, in turn, may result in a film that is generally free of separate phases, which would otherwise limit the ability of the water-soluble polymer to contact water and disperse.Type: GrantFiled: May 14, 2008Date of Patent: December 25, 2012Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Bo Shi, James H.

Patent number: 8101683Abstract: An addition-curable silicone emulsion that exhibits stable curability even with a small amount of platinum. The curable emulsion composition is composed of an emulsion A and an emulsion B described below which are mixed together at the time of use, wherein the ratio of [number-average particle size of dispersed particles in emulsion A]/[number-average particle size of dispersed particles in emulsion B] is within a range from 0.4 to 2.0. The emulsion A comprises a specific alkenyl group-containing organopolysiloxane, a specific organohydrogenpolysiloxane, a nonionic surfactant, a polyvinyl alcohol and water, wherein the number-average particle size of the dispersed particles is within a range from 300 to 1,000 nm. The emulsion B comprises a specific alkenyl group-containing organopolysiloxane, a platinum-based complex, a nonionic surfactant, a polyvinyl alcohol and water, wherein the number-average particle size of the dispersed particles is within a range from 300 to 1,000 nm.Type: GrantFiled: May 28, 2010Date of Patent: January 24, 2012Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Shinji Irifune, Tsutomu Nakajima, Kenji Yamamoto

Publication number: 20110306705Abstract: Redispersible polymer powder compositions which include a polyglycol in admixture with a redispersible polymer powder (RDP), which powder includes a codried mixture of a carboxylated, water insoluble film-forming styrene butadiene polymer and a colloidal stabilizer, results in cement compositions having unexpectedly superior overall bonding strength and adhesion after water immersion. Use of the polyglycol provides good workability or ease of troweling during application. In addition, the RDP composition, which includes the RDP and the polyglycol, provides the cement-based composition with excellent abrasion resistance, surface appearance, and color. Also, the RDP composition provides for at least a 30% reduction, for example a 50% or more reduction in the amount of retarder or retardant employed in the dry mix formulation for cement compositions, such as self leveling flooring compounds or compositions, and cement-based tile adhesives.Type: ApplicationFiled: June 14, 2011Publication date: December 15, 2011Inventors: Jürgen Dombrowski, Hartmu Kühn, Margarita Perello, Gerold A.
