    • The invention relates to a process for an additive composition comprising an amidized or imidized polymer. The invention further relates to a highly grafted, multi-functional lubricant additive useful to improve the viscosity index and dispersancy properties of a lubricating oil composition. The present invention also relates to a method of extending lubricant drain intervals and improving fuel economy and fuel economy durability. The additive composition is prepared by: (A) reacting an olefin copolymer of ethylene and at least one C3 to C23 &agr; -olefin comprising from about 15 to 80 mole percent of ethylene, from about 20 to 85 mole percent of said C3 to C23 &agr; -olefin and from about 0 to 15 wt percent of a polyene, said copolymer having a number average molecular weight ranging from 1,000 to 500,000, with an olefinic carboxylic acid acylating agent, said process comprising heating said polymer to a molten condition at a temperature in the range of 60° C. to 240° C., grafting, in a first extruder or a first mixing device, said olefinic carboxylic acylating agent onto said copolymer, optionally subsequently reducing the molecular weight of said copolymer at a temperature in the range of 250° C. to 350° C., thereby producing a grafted, reduced molecular weight acylated copolymer having a number average molecular weight ranging from 1,000 to 80,000 and having at least 0.2-20 molecules of said carboxylic acid acylating agent grafted per 1000 C atoms of said olefin copolymer, and (B) reacting, in a second extruder or a second mixing device, said acylated copolymer made in (A) with a polyamine.
    • 本发明涉及包含酰胺化或酰亚胺化聚合物的添加剂组合物的方法。 本发明还涉及可用于改善润滑油组合物的粘度指数和分散性的高度接枝的多功能润滑剂添加剂。 本发明还涉及一种延长润滑剂排放间隔并提高燃料经济性和燃料经济性的耐久性的方法。 通过以下方法制备添加剂组合物:(A)使乙烯和至少一种C3至C23的烯烃共聚物与 α-烯烃,其包含约15至80摩尔%的乙烯,约20至85摩尔%的所述C 3至C 23亚烷基; 烯烃和约0至15重量%的多烯,所述共聚物的数均分子量为1,000至500,000,与烯属羧酸酰化剂,所述方法包括将所述聚合物加热至熔融条件,温度为 在60℃至240℃的范围内,在第一挤出机或第一混合装置中将所述烯烃羧酸酰化剂接枝到所述共聚物上,任选地随后在所述共聚物的温度范围内降低所述共聚物的分子量 250℃至350℃,从而产生数均分子量为1,000至80,000并具有至少0.2-20分子的每1000个碳原子接枝的所述羧酸酰化剂的接枝的,分子量较低的酰化共聚物 的所述烯烃共聚物,和(B)在第二挤出机或第二混合装置中使(A)制成的所述酰化共聚物与多胺反应。
