ABSTRACT:
Hydroxylated polymeric additives useful as additives, for example as dispersants for lubricants and hydrocarbon fuels, and multi-functional dispersant-viscosity index improvers for lubricants, can be prepared by the reaction of metal salts of polyols with a halogen containing olefin polymer, particularly ethylene containing polymers, such as: the halogenated terpolymer of ethylene, a C.sub.3 to C.sub.18 straight or branched chain .alpha.-olefin and a C.sub.5 to C.sub.14 acyclic or alicyclic nonconjugated diolefin; a terpolymer of ethylene, a C.sub.3 to C.sub.18 alpha olefin and a C.sub.5 to C.sub.14 halogen-containing olefin; halogenated copolymers of ethylene and a C.sub.3 to C.sub.18 straight or branched chain .alpha.-olefin; etc.
