Sulfurized/aminated mixture of ethylene-based polyolefin and polyisobutylene for lubricating oil |
摘要 |
An effective amount of polyisobutylene effectively reduces polymerization and cross-linking reactions resulting in molecular weight and viscosity increase during production of dispersant viscosity index improvers by the amination and/or sulfurization of polyethylene containing polymers. |
