| 摘要 |
A multiple function polymer comprising a graft polymer of a polyolefin, a nitrogenous, ethylenically unsaturated, aliphatic or aromatic monomer having from 2 to about 50 carbon atoms, and an organo-metallic compound capable of reacting with said polyolefin is disclosed. Also disclosed is a process for making said multiple function graft polymer. Also disclosed is a lubricating oil comprising a lubricant base oil, the multiple function polymer, and optionally other dispersants. Also disclosed is a multiple function polymer comprising a graft polymer of a polyolefin, and an organo-metallic compound capable reacting with said polyolefin, and a process for making the same.
