FUEL ADDITIVE COMPOSITIONS CONTAINING AN ALIPHATIC AMINE, A POLYOLEFIN AND A POLY(OXYALKYLENE) MONOOL

摘要

A fuel additive composition comprising: (a) a fuel-soluble aliphatic hydrocarbyl-substituted amine having at least one basic nitrogen atom wherei n the hydrocarbyl group has a number average molecular weight of about 700 to 3,000; (b) a polyolefin polymer of a C2 to C6 monoolefin, wherein the polyme r has a number average molecular weight of about 350 to 3,000; and (c) a hydrocarbyl-terminated poly(oxyalkylene) monool having an average molecular weight of about 500 to about 5,000, wherein the oxyalkylene group is a C2 to C5 oxyalkylene group and the hydrocarbyl group is a C1 to C30 hydrocarbyl group.
