摘要： Liquid polymer compositions comprising: one or more hydrophobic liquids having a boiling point at least about 100 °C; at least about 39% by weight of one or more acrylamide-(co)polymers; one or more emulsifier surfactants; and one or more inverting surfactants; wherein, when the composition is inverted in an aqueous solution, it provides an inverted solution having a filter ratio using a 1.2 micron filter (FR1.2) of about 1.5 or less.

摘要： An inverse emulsion composition comprising: one or more hydrophobic liquids having a boiling point at least about 100° C.; up to about 38% by weight of one or more acrylamide-(co)polymers; one or more emulsifier surfactants; and one or more inverting surfactants; wherein, when the composition is inverted in an aqueous solution, it provides an inverted solution having a filter ratio using a 1.2 micron filter (FR 1.2) of about 1.5 or less.

摘要： Provided herein are liquid polymer (LP) compositions comprising an acrylamide (co)polymer, as well as methods for preparing inverted polymer solutions by inverting these LP compositions in an aqueous fluid. The resulting inverted polymer solutions can have a concentration of acrylamide (co)polymer of from about 50 to about 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2μm filter. Also provided are methods of using these inverted polymer solutions in dewatering, clarification, flocculation and/or thickening applications, and the like.
