(57) Abstract: [PROBLEMS] To provide a method and composition for improving mutual compatibility in oil of an olefin-based polymer and a polar polymer having a nitrogen functionality. Compositions containing the following (a), (b), (c) and (d): (a) at least one oil-soluble olefin-based polymer; (b) at least having nitrogen functionality One oil-soluble polar polymer, wherein the polymers of (a) and (b) exhibit incompatibility as evidenced by phase separation when combined with a non-polar lipophilic medium; (c) at least one substituted hydroxyaromatic material, wherein the substituent comprises at least one hydrocarbyl group and contains at least 24 carbon atoms in total; and (d) non- A polar lipophilic medium. |
