摘要：
A quaternary ammonium salt of a copolymer, said copolymer being the olefin polymerization product of:(A) a nitrogen amine free ester of a C.sub.1 -C.sub.6 olefinically unsaturated aliphatic mono-, di-, or polycarboxylic acid having a tertiary nitrogen atom; and(B) an olefinically unsaturated comonomer containing a basic nitrogen atom in a side chain;a fuel component, especially gasoline, containing such quaternary ammonium salt of such copolymer as a detergent.
