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.
