ABSTRACT OF THE DISCLOSURE The present invention relates to novel polymers which are sulfomaleic anhydride adducts of an unsaturated hydrocarbon, wherein the novel polymers are produced by contacting sulfomaleic anhydride or deri- vatives with an unsaturated hyrdocarbon to form the novel polymer, which has a ?n of about 900 to about 107. A method for controlling the viscosity of organic liquids, said organic liquid having a solubi- lity parameter of from about 6 to about 10.5, which comprises incorporating into said organic liquid a minor amount of a polymer which is a sulfomaleic anhydride adduct or sulfoester maleic anhydride adduct with an unsaturated hydrocarbon polymer, said adduct being hydrolyzed and neutralized.
