Abstract: Disclosed are soil additives capable of hydrophilizing soil particles and/or increase available water capacity in soil. The soil additive are capable of increasing the available water content/capacity (AWC) in soils, the additive in one embodiment comprising a polymer composition having a hydrophilic portion and a hydrophobic portion, wherein the hydrophobic portion of the copolymer binds with the soil particle surface and the hydrophilic portion of the copolymer can bind with water. This results in the prevention, arrest or decelerated loss of water from the targeted area, for example the plant root zone, which allows for improved water usage efficiency by plants, grasses, vegetation, etc.

Abstract: A composition for enhancing fluid viscosity including a mixture of at least one cationic or cationizable polymer and at least one anionic or anionizable (hydrolysable) polymer. The composition has a zeta potential at 25° C. in the range of 0.5 to 100 mV or −0.5 to −100 mV, typically 1 to 60 mV or −1 to −60 mV, or is a precursor convertible at a temperature of 100 to 250° C. to the composition having a zeta potential at 25° C. of 0.5 to 100 mV or −0.5 to −100 mV, typically 1 to 60 mV or −1 to −60 mV. Typically the compositions exhibit salt tolerance and interaction of both polymers at very high temperatures (>300° F.) such that the system exhibits an increase of viscosity at extreme temperatures. The compositions are useful for hydraulic fracturing, enhanced oil recovery, subterranean acidization, personal care as well as home and industrial cleaners.
