Lactone-modified, mannich base dispersant additives useful in oleaginous compositions
First Claim
1. A poly(C5 -C9 lactone) modified Mannich base useful as an oil additive and formed by reacting a C5 -C9 lactone, an amine, an aldehyde, and a hydrocarbyl hydroxy aromatic compound, said hydrocarbyl substituted hydroxy aromatic compound being formed by reacting an olefin polymer of a C2 -C10 monoolefin having a number average molecular weight of about 700 to about 10,000 and a hydroxy aromatic material, and said poly (C5 -C9 lactone) modified Mannich base adduct containing the unit ##STR14## wherein m has a average value of from 0.2 to about 100, and z is 4 to 8.

Abstract
Poly (C5 -C9 lactone) modified Mannich base adducts are made by reacting a C5 -C9 lactone, an amine, an aldehyde, and a hydrocarbyl substituted, hydroxy aromatic compound, e.g. a polyisobutenyl phenol which, in turn, preferably is made by reacting a polymer of a C2 to C10 monoolefin, preferably polyisobutylene, having a molecular weight of about 700 to 10,000, with a hydroxy aromatic compound. The resulting adducts are useful per se as oil soluble dispersant additives. They are also useful in fuel and lubricating oil compositions, as well as in concentrates and additive packages.
