中国专剂CN1128273A报道了一项发明是涉及用作润滑油粘度指数改进剂的氢化丁苯共聚物的制造方法.是采用乙二醇二甲醚类强极性结构调节剂、有机理引发剂及惰性溶剂,使丁二烯和苯乙烯共聚,在聚合过程中避免物料与二氧化碳、空气或氧气等接触,避免聚合液在聚合釜或管线中残留,然后将所得的丁苯共聚物进行加氢,即制得丁苯粘度指数改进剂.这方法制得的丁苯粘度指数改进剂具有良好的化学稳定性、耐氧化性、耐老化性、油溶性和配伍性好,可用于润滑油的增稠,并大大提高润滑油的粘温性能,有很好的应用前景.
Chinese patent CN1128273A reports that an invention relates to a method for preparing a hydrogenated styrene-butadiene copolymer which is used as a lubricant viscosity index improver, which comprises ethylene glycol dimethyl ether strong polarity structural modifiers, a mechanism initiator and Inert solvent, butadiene and styrene copolymerization, during the polymerization to avoid the material with carbon dioxide, air or oxygen and other contacts, to avoid polymerization liquid in the polymerization vessel or pipeline residue, and then the resulting styrene-butadiene copolymer hydrogenation, Which is made of butyl benzene viscosity index improver.This method produces butyl benzene viscosity index improver has good chemical stability, oxidation resistance, aging resistance, oil solubility and compatibility, can be used for thickening of lubricating oil , And greatly improve the viscosity of the lubricating oil properties, have good prospects.
