Zusammenfassung:	Use of hydrophobically modified polyalkanolamines obtainable by condensing at least one trialkanolamine and optionally further condensable monomers and reacting at least one of the terminal OH groups with suitable reactants capable of reacting with OH groups and comprising long chain hydrocarbon groups as wax inhibitor, pour point depressant and additive for lubricants. L'utilisation de polyalcanolamines modifiées de manière hydrophobe peuvent être obtenues par condensation d'au moins une trialcanolamine et éventuellement d'autres monomères condensables et par réaction d'au moins un des groupes OH terminaux avec des réactifs appropriés capables de réagir avec des groupes OH et comprenant des groupes hydrocarbonés à chaîne longue en tant qu'inhibiteur de cire, additif abaissant le point d'écoulement et additif pour lubrifiants.
