Abstract:
A liquid composition exhibiting reversible solution/emulsion phase transition to provide a relatively constant viscosity/temperature relationship is provided with a hydrocarbon oil and a minor amount of an interpolymer of at least one hydrocarbon monomer and at least one dispersant monomer having an oil soluble pendant moiety wherein the interpolymer is soluble in the oil above a characteristic transition temperature and wherein the dispersant monomer is in sufficient amount to maintain the interpolymer in a stable colloidal dispersion below that transition temperature.
