ABSTRACT:
A method for controlling the viscosity of organic liquids, said organic liquid having a solubility parameter of less than 9.5, a viscosity, as measured at 25.degree. C., of less than 200 centipoises and said organic liquid is selected from the group consisting of mineral oils, synthetic oils, naphthanes, alkanes, cycloalkanes and aromatics and mixtures thereof, which comprises incorporating in said organic liquid about 0.01 to 20 grams of polymer complex per 100 ml. of said organic liquid, said polymer complex being formed "in situ" in said organic liquid or dissolved in said organic liquid, said complex being comprised of polymer A, containing about 4 meq. to 500 meq. of neutralized sulfonate groups, and polymer B, containing basic nitrogen groups, both functional groups being present at a level of from about 4 to 500 meq. per 100 g. of polymer, wherein polymer B has the formula: ##STR1## wherein x is about 50.0 to 99.8 weight percent and y is about 0.2 to about 50.0 weight percent, wherein said sulfonate groups of said polymer A being neutralized with basic compounds selected from the group consisting of transition elements, said polymer A having a polymeric backbone substantially soluble in said organic liquid and said polymer having a molecular weight of about 1,000 to 10,000,000.
