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.
Claims20
A polymeric gel having increased viscosity provided by an auxiliary rheological additive comprising approximately by weight:
- (a) 0.1 to 10.0 weight percent of an anionic polymer at least partially neutralized through the addition of at least one organic base to neutralize said anionic polymer and to form a gel;
- and
- (b) 0.1 to 10.0 percent by weight of an amphoteric oxide auxiliary rheological additive;
- and
- (c) the balance being at least one predominantly organic solvent wherein the viscosity of the polymeric gel is increased from about 10 to 300 percent of the viscosity of a similar gel which does not contain the auxiliary rheological additive, said polymeric gel having a viscosity of 33,200 cps and greater and flows less than 5 cm when said polymeric gel is heated to 38.degree. C..+-.3.degree. C. for 24 hours and the container holding said polymeric gel is inverted for three minutes.
