ABSTRACT:
The novel polymers of the present invention are prepared by reacting a hydroxy aromatic compound containing at least one --OH group in the ring, an aldehyde and amino-substituted polymer (e.g., an ethylene alpha-olefin interpolymer substituted by primary amino or secondary amino groups) to form an oil soluble Mannich base derivative useful as antioxidant dispersant viscosity modifier additive in oleaginous compositions such as lubricating oils and fuels. Preferred aromatic compounds are phenols such as 2,6-di-t-butylphenol or 2,6-dimethylphenol. Preferred amino-substituted interpolymers comprise amino-substituted ethylene propylene norbornene terpolymers.
