摘要： Provided herein are polyimide dispersants, as well as methods for producing polyimide dispersants. The polyimides can be defined by the formula below wherein A, individually for each occurrence, represents a cyclic diimide moiety represented by the structure below where B represents a cyclic moiety substituted with a first cyclic imide group and a second cyclic imide group; Y, individually for each occurrence, represents a bivalent linking group; L, individually for each occurrence, is absent or represents a cyclic imide group; R, individually for each occurrence, represents a polymeric tail; and n is an integer from 1 to 20.

摘要： Provided herein are polyolefin dispersants, as well as methods for producing polyolefin dispersants. The polyolefin dispersants can be defined by the formula below where Rx is cationic initiator residue; Ra is a polyolefin group; R1 and R2 are each, independently in each —(CR1R2) unit, H, alkyl, alkoxy, or alkylaryl; R3 and R4 are each, independently, H, alkyl, or alkoxy; m is an integer from 1 to 20; n is an integer from 1 to 6; r is an integer from 1 to 4; Y is a polyvalent amine linker comprising one or more tertiary amines, wherein the polyvalent amine linker does not include a primary amine or a secondary amine; and A is absent, or comprises a dispersive moiety.

摘要： 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.
