VON DIHYDROXYAROMATISCHEN VERBINDUNGEN HERKOMMENDE BRENNSTOFF- UND SCHMIERMITTELZUSÄTZE
摘要
<p>The present invention relates to a novel process for the production of fuel and lubricant additives useful as dispersants and multifunctional viscosity modifiers wherein a dihydroxyaromatic compound is alkylated with an olefinic polymer and then aminated in such a manner as to oxidize the hydroxyl moieties of the dihydroxyaromatic compound to carbonyl groups.</p>
