  • Responsive polymer networks and methods of their use
    Patent number: 5939485
    Abstract: A responsive polymer network exhibiting the property of reversible gelation in response to a change in an environmental stimulus is provided. The aqueous solution of the network polymer, comprises about 0.01 to 20 wt % by weight of a responsive component and about 0.01 to 20 wt % by weight of a structural component capable of supporting and interacting with the responsive component. The aqueous composition exhibits at least a five-fold increase in viscosity upon gelation. The gelation may be triggered by a change in an environmental stimulus, such as temperature, pH and ionic strength.
