Abstract
Abstract 1. A COMPOSITION COMPRISING A MAJOR AMOUNT OF A HYDROCARBON FUEL OR LUBRICATING OIL AND .001 TO 45 WT. PERCENT OF AN OIL SOLUBLE ADDUCT OF AN EPOXIDIZED TERPOLYMER, USEFUL AS A LUBRICANT OR FLUEL ADDITIVE, SAID TERPOLYMER HAVING A MOLECULAR WEIGHT IN THE RANGE OF 10.000 TO 1,000,000 VISCOSITY AVERAGE MOLECULAR WEIGHT AND COMPRISING IN THE RANGE OF ABOUT 30 TO 85 MOLE PERCENT ETHYLENE, ABOUT 14.5 TO ABOUT 69.5 MOLE PERCENT OF A C3 TO C8 ALPHA MONOOLEFIN AND ABOUT 0.5 TO ABOUT 20 MOLE PERCENT OF A C5 TO C14 NON-CONJUGATED DIOLEFIN, WHEREIN ABOUT 10 TO 100% OF THE DOUBLE BONDS IN THE TERPOLYMER HAVE BEEN EPOXIDIZED, AND ABOUT 10 TO 100% OF THE EPOXIDIZED GROUPS HAVE BEEN REACTED WITH A C1 TO C18 AMINE WHICH CONTAINS 1 TO 8 NITROGEN ATOMS TO FORM SAID ADDUCT.
