Publication number: 20100324166Abstract: This invention discloses, compositions of aqueous fluids comprising one or more dispersion polymer(s), wherein the dispersion polymer comprises 96 to 100 mole percent of one or more nonionic monomer units and 0 to 4 mole percent of one or more cationic or anionic monomer units; and has a molecular weight of at least 100,000. The invention also discloses the method(s) of using one or more such dispersion polymer(s), comprising adding to or mixing with the aqueous fluid a friction-reducing amount of the polymer(s), before, during or after a turbulent flow is induced. Nonionic dispersion polymers consistently render substantially greater extents of friction reduction than their ionic counterparts. A dispersion polymer (formed by dispersion polymerization) provides up to four times as much friction reduction as the same polymer in solution when used at the same dosage.Type: ApplicationFiled: June 18, 2010Publication date: December 23, 2010Applicant: CHAMPION TECHNOLOGIES, INC.Inventor: Jun Jim Wu

Publication number: 20100316802Abstract: It is disclosed an over-coating agent for forming fine patterns which is applied to cover a substrate having thereon photoresist patterns and allowed to shrink under heat so that the spacing between adjacent photoresist patterns is lessened, with the applied film of the over-coating agent being removed substantially completely to form or define fine trace patterns, further characterized by containing either a water-soluble polymer and an amide group-containing monomer or a water-soluble polymer which contains at least (meth)acrylamide as a monomeric component. Also disclosed is a method of forming fine-line patterns using any one of said over-coating agents. According to the invention, the thermal shrinkage of the over-coating agent for forming fine patterns in the heat treatment can be extensively increased, and one can obtain fine-line patterns which exhibit good profiles while satisfying the characteristics required of semiconductor devices.Type: ApplicationFiled: August 24, 2010Publication date: December 16, 2010Inventors: Yoshiki Sugeta, Fumitake Kaneko, Toshikazu Tachikawa

Publication number: 20100311889Abstract: The invention consists of a method for manufacturing a paper coating slip containing a mineral material, using, as an agent for thickening the slip, a water-soluble polymer comprising at least one ethylene-unsaturated anionic monomer, and at least one ethylene-unsaturated oxyalkyl monomer terminating in a branched hydrophobic alkyl, alkaryl, arylalkyl, aryl chain, saturated or unsaturated, with 14 to 21 carbon atoms and two branches each with at least six carbon atoms. The polymer is added to the slip either directly, or during a prior stage when grinding, dispersing, or concentrating the mineral material in water, which may or not be followed by a drying stage. In this way, the water retention of the slip is improved, which contributes to a better printability of the paper coated by the slip.Type: ApplicationFiled: December 2, 2008Publication date: December 9, 2010Inventors: Patrick Arthur Charles Gane, Jean-Marc Suau
