1. A composition comprising a mixture of a first and a second hydrophobically modified alkylene oxide polymer, wherein the first hydrophobically modified alkylene oxide polymer is endcapped with at least one first hydrophobic group functionalized with a secondary amine or a salt thereof, or a tertiary amine or a salt thereof; and wherein the second hydrophobically modified alkylene oxide polymer is endcapped with at least one second hydrophobic group, structure I:

OG Complex Work Unit Chemistry
wherein the dotted line represents the point of attachment of the hydrophobic group of structure I to the alkylene oxide polymer backbone; where R1 is from C1-C10-alkyl; R2 is from C1-C6-alkyl; m is from 5 to 40; and n is from 0 to 50, with the proviso that when m is from 5 to 9, n is from 0 to 10, wherein the first and second hydrophobically modified alkylene oxide polymers are hydrophobically modified ethylene oxide urethane polymers, and wherein the mole: mole ratio of first hydrophobic groups to second hydrophobic groups is in the range of from 15:85 to 75:25.
