Fuels for gasoline engines |
摘要 |
Fuels for gasoline engines contain small amounts of copolymers of alkyl (meth)-acrylates where the alkyl radical is of 8 to 40 carbon atoms and/or vinyl esters of carboxylic acids of 8 to 40 carbon atoms and monoethylenically unsaturated mono- and/or dicarboxylic acids of 3 to 12 carbon atoms and/or monoethylenically unsaturated compounds having sulfo and/or phosphonic acid groups, having a total molecular weight of from 500 to 20,000 g per mole, some or all of the carboxyl, sulfo and phosphonic acid groups of the copolymers having been reacted with an alkali or alkaline earth with formation of the alkali metla salts or alkaline earth metal salts and the remainder of the acid groups having been reacted with ammonia and/or amines of not more than 50 carbon atoms to give the corresponding amide groups and/or ammonium salts.
