Abstract

Improving the flowability of mineral oils and mineral oil distillates using alkylphenol-aldehyde resins The invention relates to a process for improving the flowability of paraffin-containing mineral oils and mineral oil distillates by adding flow improvers based on ethylene/vinyl ester co- and terpolymers, alkylphenol-aldehyde resins and, if appropriate, other paraffin dispersants, mixtures of these different flow improvers and mineral oils and mineral oil distillates which comprise these flow improvers.
