Polymer additives for engine oils
- Texaco R and D, Beacon, NY (United States)
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.
