  • Patent number: 5773706
    Abstract: Organic liquids can be very effectively gelled by using in combination with an amine neutralized anionic polymer an auxiliary rheological additive. The auxiliary rheological additive is a substance which increases the linearity of the anionic polymer and its thixotropic properties. Suitable auxiliary rheological additives are amphoteric oxides and/or fatty acids and/or fatty acid salts. The organic liquids that can be effectively gelled are organic solvents which include fuels such as hydrocarbons and alcohols.
