Poly (Cs-C9 lactone) modified Mannich base adducts are made by reacting a C5-C9 lactone, an amine, an aldehyde, an N-hydroxyaryiamine, and a hydrocarbyl substituted C4-C10 monounsaturated dicarboxylic acid producing material, e.g., a polyisobutenyl succinic anhydride, which, in turn, preferably is made by reacting a polymer of a C2 to C1 0 monoolefin, preferably polyisobutylene, having a molecular weight of about 700 to 10,000 with a C4 to C10 monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are about 0.7 to 2.00 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting adducts are useful per se as oil soluble dispersant additives. They are also useful in fuel and lubricating oil compositions, as well as in concentrates and additive packages.
聚(Cs-C9 内酯)改性曼尼希碱加合物是由 C5-C9 内酯、胺、醛、N-羟基芳香胺和烃基取代的 C4-C10 单不饱和二
羧酸生成物,例如:聚
异丁烯基
琥珀酸酐反应而成、聚
异丁烯基
琥珀酸酐,它又最好是由分子量约为 700 至 10,000 的 C2 至 C1 0 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)反应而成,使反应混合物中使用的每分子所述烯烃聚合物中约有 0.7 至 2.00 个产生二
羧酸的分子。生成的加合物本身可用作油溶性分散剂添加剂。它们还可用于燃料和润滑油组合物以及浓缩物和复合添加剂。
