20110066540 | Methods, Software, and Systems for Over-the-Counter Trading - Methods, software, and hardware are disclosed for providing verified real time price quotes in an over-the-counter financial market. Systems are described that can comprise methods, software, and/or hardware to provide verified real time price information for securities traded over-the-counter. Verification methods of the invention include identifying suspect source data, wherein the suspect source data includes information about the price of a security, verifying the suspect source data, and displaying to a user a verified price quote of a security traded in an over-the-counter market to a user. The verification methods of the invention include using hash functions and hash tables to process suspect source data, wherein the hashing allows for confidential processing while at the same time maintaining the ability to match a price quote to the source of the price quote. | 03-17-2011 |

20080306218 | Aqueous emulsion polymer associative thickeners - An aqueous emulsion polymer suitable for use in thickening aqueous compositions including, as copolymerized units: from 8% to 25 wt %, based on polymer weight, acid-containing monomer, from 2% to 30 wt %, based on polymer weight, (meth)acrylic acid ester of the formula: H | 12-11-2008 |
20100286434 | Ethylenically unsaturated monomers for thickener compositions - New ethylenically unsaturated monomers are provided that can be (co)polymerized to provide a composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened. The thickeners are prepared from the novel monomers by an aqueous solution polymerization. | 11-11-2010 |
20110281980 | Thickener composition and method for thickening aqueous systems - A composition and method whereby the same group that is attached to or within the backbone of an associative thickener is reversibly switched between being hydrophilic and hydrophobic in nature. When the group that is attached to or within the backbone is rendered hydrophilic, the aqueous thickener is pourable and readily incorporated into aqueous polymer compositions. When this group is rendered hydrophobic, the thickener performs its thickening function efficiently. Switching is readily accomplished by adjusting the pH of the associative thickener composition and the aqueous polymer composition being thickened. The thickeners may be prepared from monomers by an all-aqueous solution polymerization. | 11-17-2011 |
20150307733 | AMPHOTERIC POLYMER PARTICLES AND COMPOSITIONS THEREOF - The present invention relates to a stable aqueous dispersion of multiphase amphoteric polymer particles comprising a crosslinked polymer phase comprising structural units of a phosphorus acid monomer, a carboxylic acid monomer, a multiethylenically unsaturated monomer, and an ethylenically unsaturated nonionic monomer; and a second polymer phase comprising a carboxylic acid monomer and an ethylenically unsaturated nonionic monomer. The present invention also relates to composites of the particles and pigment particles such as TiO | 10-29-2015 |
