MANNICH BASE POLYMERS |
摘要 |
A process for producing an oil soluble interpolymer polymer of 1,2alkylenediamine such as N-ethyl ethylenediamine, aldehyde-provider such as formaldehyde, and ortho-unsubstituted hydroxyaromatics such as 4-polyalkylene phenol is disclosed. The decyclized Mannich Base monomer units provide a higher viscosity material which is suitably substituted with a long chain hydrocarbyl para substituent such as polyisobutylene or ethylene/alpha-olefin polymer. Various ortho-substituted hydroxyaromatics such as o-cresol may be used to control the degree of polymerization. The polymers are useful as dispersants or other lubricant additives.
