Publication number: 20150148455Abstract: The invention relates mainly to a polymer comprising a hydrocarbon-based main chain bearing carboxylic groups and polyalkoxylated chains and up to 4% by weight of anti-oxidant groups, relative to the weight of the final polymer, grafted to the main chain. It also relates to a method for preparing such a polymer and to an admixture which is of use as a plasticizer of suspensions of mineral particles comprising same. Finally, it is related to the use of such a polymer for fluidifying suspensions of mineral particles and reducing the water demand of hydraulic compositions.Type: ApplicationFiled: August 9, 2012Publication date: May 28, 2015Applicant: CHRYSOInventors: Alexandre Desseroir, Philippe Maitrasse, Marc Lemaire, Florence Popowycz, PIERRE Labourt-Ibarre

Publication number: 20150111792Abstract: Spray dried emulsifier compositions are described, which have desirable emulsifying and wetting characteristics. Among other advantages, the solid particulate emulsifier compositions greatly reduce transportation costs and simplify the logistics and environmental concerns associated with shipping large volumes of solvent-containing liquids. The emulsifier comprises (1) a carboxylic acid terminated fatty amine condensate or (2) a modified tall oil or (3) a blend of (1) and (2) that is converted to its alkali or alkaline earth metal salt and spray dried.Type: ApplicationFiled: December 30, 2014Publication date: April 23, 2015Applicant: Georgia-Pacific Chemicals LLCInventors: Phillip W. Hurd, Gary D. Fultz, Jalandar Jadhav
