FLUID ADDITIVE COMPOSITION

摘要

A fluid additive composition including one or more dispersing agents in a stabilization effective dose is provided to realize a fluid additive composition having satisfactory stability. A fluid additive composition includes one or more dispersing agents including terminal vinylidene more than 50% in a stabilization effective dose, wherein the one or more dispersing agents are manufactured by reacting one or more hydrocarbyl substitution acylation agents and one or more amines. The dispersing agents are acylated amines having one or more hydrocarbyl substitution acylation agents and one or more amino nitrogens in a structure thereof. The acylated amines are manufactured by making one or more amines exceeding about 1 equivalent react with each equivalent of carboxylic acid of one or more hydrocarbyl substitution acylation agents. One or more hydrocarbyl substitution acylation agents are polyolefine having polydispersity and 600-5000 of number mean molecular weight.
