20110319669 | BRANCHED SECONDARY ALCOHOL ALKOXYLATE SURFACTANTS AND PROCESS TO MAKE THEM - Provided are alkoxylates of the formula I: | 12-29-2011 |
20120196779 | Cutting Fluids with Improved Performance - The cutting of semi-conducting crystals with a wire saw is facilitated with a cutting fluid comprising a polyalkylene glycol neutralized with an un-neutralized or partially neutralized polymeric acid that has a molecular weight of 500 to 1,000,000 and contains more than three acid groups per molecule. | 08-02-2012 |
20120214385 | Polyalkylene Glycol-Grafted Polycarboxylate Suspension and Dispersing Agent for Cutting Fluids and Slurries - Cutting fluids for brittle materials, e.g., silicon ingot, comprise, in weight percent: A. 70-99% polyalkylene glycol (PAG), e.g., polyethylene glycol; B. 0.01-10% PAG-grafted polycarboxylate; and C. 0-30% water. These cutting fluids are used with abrasive materials, e.g., silicon carbide (SiC), to form cutting slurries. The slurry is sprayed on the cutting tool, e.g., a wire saw, to cut a brittle work piece, e.g., a silicon ingot. | 08-23-2012 |
20130060000 | METHODS FOR PRODUCING CROSSLINKABLE SILYL GROUP-CONTAINING POLYOXYALKYLENE POLYMERS - Embodiments of the invention provide for a method of producing a silylated polyoxyalkylene polymer having at least one crosslinkable silyl group and at least one hydroxyl group in each molecule. The method comprises providing a polyoxyalkylene polymer having at least one unsaturated group and at least one alcoholic hydroxyl group in each molecule, wherein the polyoxyalkylene polymer includes an impurity double metal cyanide complex mixed therein, and wherein the polyoxyalkylene polymer has not been treated with a metal-coordinating compound; and adding to the polyoxyalkylene polymer a compound having a hydrogen-silicon bond and a crosslinkable silyl group in each molecule and a hydrosilylation catalyst to thereby carry out a hydrosilylation reaction, wherein the hydrosilyation reaction is performed in an absence of a metal-coordinating compound. | 03-07-2013 |
20130231508 | BRANCHED SECONDARY ALCOHOL ALKOXYLATE SURFACTANTS AND PROCESS TO MAKE THEM - Provided are alkoxylates of the formula I: Also provided is a process for making alkoxylates of formula I. The process provides alkoxylates that exhibit narrow molecular weight distribution and low amounts of residual unreacted alcohol. The alkoxylates have utility in a variety of applications, such as use as surfactants. | 09-05-2013 |
20140256944 | PROCESS FOR MAKING ALKOXYLATED PIPERAZINE COMPOUNDS - The present invention relates to an improved process for making mono- and di-alkoxylated piperazine compounds especially dihydroxyethylpiperazine. The improvement comprises the addition of an acid to the piperazine compound prior to the addition of an alkylene oxide to a reactor wherein the alkoxylated piperazine compound is prepared. Said improvement reduces the concentration of undesirable glycol ether byproducts which contribute undesirable color and foaming of the alkoxylated piperazine compounds. | 09-11-2014 |
20140330042 | PROCESS FOR MAKING ETHOXYLATED AMINE COMPOUNDS - An improved process for making ethoxylated amine compounds such as ethanolamines. The improvement comprises the addition of an acid to the amine compound prior to the addition of ethylene oxide to a reactor wherein the ethoxylated amine compound is prepared. The improvement reduces the concentration of undesirable glycol ether and/or vinyl ether ethoxylate byproducts which may contribute to undesirable properties, such as color and foaming, of the ethoxylated amine compounds. | 11-06-2014 |
20150232776 | AMINE ALKOXYLATE COMPOSITIONS AND THEIR USE AS LUBRICANT ADDITIVES - Provided are compositions and their use as dispersant and/or detergent additives for lubricants. The compositions comprise an amine alkoxylate of the formula I: (I) wherein R | 08-20-2015 |
