摘要：
A lubricant composition comprises an ethylene/α-olefin interpolymer having a number average molecular weight of less than 10,000 g/mol as a base oil and at least one oil additive. The ethylene/α-olefin interpolymer has at least one molecular fraction which elutes between 40°C and 130°C when fractionated using TREF, characterized in that the fraction has a molar comonomer content of at least 5 percent higher than that of a comparable random ethylene interpolymer fraction eluting between the same temperatures, wherein said comparable random ethylene interpolymer has the same comonomer(s) and has a melt index, density, and molar comonomer content (based on the whole polymer) within 10 percent of that of the ethylene/α-olefÊn interpolymer.
摘要（中）：
润滑剂组合物包含数均分子量小于10,000g / mol的基础油和至少一种油添加剂的乙烯/α-烯烃互聚物。 当使用TREF分馏时，乙烯/α-烯烃互聚物具有至少一种在40℃和130℃之间洗脱的分子级分，其特征在于该级分的摩尔共聚单体含量比可比较的随机值高出至少5％ 在相同温度下洗脱的乙烯互聚物级分，其中所述可比较的无规乙烯互聚物具有相同的共聚单体，并且其熔体指数，密度和摩尔共聚单体含量（基于全部聚合物）在乙烯/ α-烯烃互聚物。
