聚合物和低聚物是石油工业的一个重要研究领域，多年来已经发现了它们的许多用途。聚合物的一个重要应用是曲轴箱润滑剂，其中各种特种聚合物和共聚物用作粘度调节剂、分散剂和倾点下降剂。这些聚合物赋予润滑油全天候的性能，是生产多级润滑油最有效的添加剂。聚合物结构可被改性以产生多官能聚合物添加剂，其改善粘度指数并赋予油其它性质（即，分散性、抗氧化剂和抗磨性能）。在这篇文章中，作者将介绍聚合物在曲轴箱润滑油中的作用，然后描述德士古在该领域所做的一些工作。
Polymers and oligomers are an important area of research for the oil industry, and many uses for them have been discovered over the years. One important application for polymers is in crankcase lubricants, in which various specialty polymers and copolymers are used as viscosity modifiers, dispersants, and pour-point depressants. These polymers give an oil all-season properties and are the most effective additives in producing multigrade oils. Polymer structures can be modified to produce multi-functional polymer additives that improve the viscosity index and impart other properties to the oil (i.e., dispersancy, antioxidant, and antiwear properties). In this article the authors will present an overview of the role of polymers in crankcase lubricants and then describe some work Texaco has done in the field.
