Olefin Copolymer (OCP) Viscosity Index Improvers with Optimized Performance – (PPT)

摘要

Polymer structure property studies have been used to develop high performance, optimized OCP for VII application. Optimized Low SSI OCP: Unique structure properties; Ethylene content, ethylene distribution, and branching. Optimized for heavy duty Application: Good thickening, low piston deposits, robust low temperature properties, extended shear durability. Optimized High SSI OCP: Unique structure properties, Ethylene content and block character; Optimized for passenger car Application: Exceptional thickening, low CCS, fuel economy.
