Abstract
Official abstract text for this publication.
The present invention relates to a composition comprising an aqueous solution of a) a hydrophobically modified alkylene oxide polymer comprising a hydrophobic portion functionalized with a protonated secondary or tertiary amine or a quaternary ammonium salt and b) an acid and a salt thereof, which acid is phosphoric acid, nitrilotris(methylene)triphosphonic acid, hydrochloric acid, or sulfuric acid. The composition of the present invention is useful for the preparation of an associative thickener that can be stored for long periods, in the absence of ancillary biocides, without spoilage from biodeteriogenic attack.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising an aqueous solution of a) a hydrophobically modified ethylene oxide urethane polymer comprising a hydrophobic portion functionalized with a protonated secondary or protonated tertiary amine or a quaternary ammonium salt and b) phosphoric acid or a salt thereof, wherein the composition has a pH in the range of from 2.0 to 2.8. 2. The composition of claim 1 wherein the hydrophobic portion of the hydrophobically modified ethylene oxide urethane polymer is functionalized with a protonated tertiary amine. 3. The composition of claim 2 wherein the pH of the composition is in the range of from 2.1 to 2.7. 4. The composition of claim 3 which has a pH in the range of from 2.1 to 2.5.
