Abstract

Ethylene-C-Calpha olefin copolymers, dispersants and lubricating oils/fuel compositions incorporating dispersants, and related methods are generally described herein. The copolymer may comprise ethylene-derived units and C-Calpha-olefin-derived units. The C-Calpha-olefin-derived units may have a carbon number from three to ten. For example, the C-Calpha-olefin-derived units may be propylene-derived units.
