DISPERSANT - V.I. IMPROVER PREPARED VIA OZONIZATION

摘要

ABSTRACTLubricating oil additives having both dispersa?t and viscosity-index improving properties are prepared by ozonizing a terpolymer of ethylene,a C3 to C8 alpha-olefin, and a non-conjugated diene, and reacting the ozonizedterpolymer with certain amines, or alkane polyols. Optionally, the ozonizedterpolymer can be reacted with oxygen before reaction with the amine or polyol.
