    Abstract: The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated, functionalized, optionally modified and post treated. The dispersant substances include a copolymer of two different conjugated dienes. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. The polymers may be functionalized by a Mannich base condensation reaction. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.

    Abstract translation: 本发明提供分散剂和分散剂粘度指数改进剂,其包括已被氢化,官能化,任选改性和后处理的共轭二烯的聚合物。 分散剂物质包括两种不同共轭二烯的共聚物。 聚合物被选择性氢化以产生具有高度受控量的不饱和度的聚合物,允许高选择性官能化。 聚合物可以通过曼尼希碱缩合反应来官能化。 还提供了通过本发明的分散剂物质改性其分散性和/或粘度特性的润滑剂流体,例如矿物油和合成油。 还提供了改变润滑流体如矿物和合成润滑油的分散性和/或粘度特性的方法。 分散剂物质还可以包括提供分散剂浓缩物的载体流体。
