C₅-C₉ lactone based adduct materials are made by reacting a C₅-C₉ lactone with a polyamine, a polyol or an amino alcohol to form a lactone adduct intermediate, and thereafter reacting the intermediate with a hydrocarbyl substituted C₄-C₁₀ monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl succinimide, which, in turn, preferably was made by reacting a polymer of a C₂ to C₁₀ monoolefin, preferably polyisobutylene, having a molecular weight of about 300 to 10,000 with a C₄ to C₁₀ monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are 0.7 to 2.0 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting adduct material are useful per se, as oil soluble dispersant additives, and are useful in fuel and lubricating oil compositions including concentrates containing the additives.
C₅-C₉内酯基加合物材料是通过使 C₅-C₉内酯与多胺、多元醇或氨基醇反应形成内酯加合物中间体,然后使该中间体与烃基取代的 C₄-C₁₀单不饱和二羧酸生产材料(例如)反应制成的、聚异丁烯基琥珀酰亚胺,而聚异丁烯基琥珀酰亚胺最好是通过将分子量约为 300 至 10,000 的 C₂ 至 C₁₀ 单烯烃(最好是聚异丁烯)聚合物与 C₄ 至 C₁₀ 单不饱和酸、酐或酯(最好是马来酸酐)反应制成,从而产生 0.在反应混合物中,每分子所述烯烃聚合物含有 0.7 至 2.0 个产生二羧酸的分子。生成的加成材料本身可用作油溶性分散剂添加剂,也可用于燃料和润滑油组合物,包括含有添加剂的浓缩物。
