Publication number: 20090286906Abstract: 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: ApplicationFiled: May 14, 2008Publication date: November 19, 2009Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Bo Shi, James H.

Publication number: 20090227718Abstract: Disclosed is a polyvinyl alcohol aqueous dispersion having excellent storage stability which is capable of forming a coating film with excellent water resistance and transparency even when it is dried at room temperature. Also disclosed are a composition and a coating agent for paper. Specifically disclosed is an aqueous dispersion of a resin which is composed of a polymer containing at least 20 weight % of a vinyl monomer unit (A) having an epoxy group and a vinyl alcohol polymer (B) while having a weight ratio (A)/(B) of 2/100-200/100. The weight ratio of (A) bonded to (B) is not less than 50% relative to the total weight of (A), and the average particle size of the resin determined by dynamic light scattering is not more than 500 nm.Type: ApplicationFiled: May 16, 2005Publication date: September 10, 2009Applicant: Kuraray Co.LTD.Inventors: Seiji Tanimoto, Naoki Fujiwara

Patent number: RE40920Abstract: New anti-reflective or fill compositions having improved flow properties are provided. The compositions comprise a styrene-allyl alcohol polymer and preferably at least one other polymer (e.g., cellulosic polymers) in addition to the styrene-allyl alcohol polymer. The inventive compositions can be used to protect contact or via holes from degradation during subsequent etching in the dual damascene process. The inventive compositions can also be applied to substrates (e.g., silicon wafers) to form anti-reflective coating layers having high etch rates which minimize or prevent reflection during subsequent photoresist exposure and developing.Type: GrantFiled: May 1, 2007Date of Patent: September 22, 2009Assignee: Brewer Science Inc.Inventors: Gu Xu, Jimmy D. Meador, Mandar R. Bhave, Shreeram V. Deshpande, Kelly A. Nowak

Patent number: RE40941Abstract: The present invention includes processes and resulting structures for producing a modified polymer having interconnecting channels. The interconnecting channels act as controlled transmission passages through the polymer. A hydrophilic agent is blended into the polymer so that it is distributed within the polymer. In one embodiment, a releasing material is blended into the polymer so that the releasing material is distributed within the product. The product is solidified so that the hydrophilic agent forms passages in the product through which a desired composition is communicable to the releasing material that is entrained within the product. The solidified product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet.Type: GrantFiled: November 13, 2003Date of Patent: October 20, 2009Assignee: CSP Technologies, Inc.Inventor: Ihab Hekal
