Amine-functionalized polymers |
| 摘要 |
A method is disclosed for preparation of amine functionalized copolymers by reacting copolymers of alkyl methacrylate and maleic anhydride with N-phenyl-1,4-phenylenediamine in mineral oil and inert atmosphere at 40 to 75 DEG C. The copolymers are useful viscosity index improvers when incorporated into lubricating oils.
