Disclosed is a dispersant composition, suitable for use in lubricating oils. The dispersant composition is a reaction product of (i) a polyalkenyl succinimide post-treated with a post-treating agent selected from the group consisting of an organic carbonate, an epoxide, a lactone, a hydroxyaliphatic carboxylic acid, and combinations thereof; and (ii) an acylating agent.

Dispersants, method of making, and using same

Provided herein are methods for preparing a functionalized polyolefin from an unsaturated polyolefin containing one or more non-aromatic main-chain double bonds and for reducing the size and/or polydispersity index (i.e., increasing the homogeneity) of the unsaturated polyolefin.

Methods of preparing functionalized polyolefins

Provided herein are copolymers of a polyaminopolymer and polyanhydride, wherein the polyaminopolymer comprises a polyaminopolyolefin; and methods of their preparation.

Copolymers of polyaminopolyolefins and polyanhydrides and methods of their preparation

Provided herein are methods for the preparation of telechelic polyolefins via polymerization reaction with a terpene initiator.

Methods for producing telechelic polyolefins from terpene initiators

Provided herein are methods for the preparation of mono- and multi-functional telechelic polyolefins via polymerization reaction with a terpene-based initiator.
