ABSTRACT:
Poly (C.sub.5 -C.sub.9 lactone) modified Mannich base adducts are made by reacting a C.sub.5 -C.sub.9 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 C.sub.2 to C.sub.10 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.
