ABSTRACT:
The present invention provides a continuous process for preparing additive mixtures for mineral oils and mineral oil distillates, comprisingA) a cold flow improver for middle distillates, and at least one further component selected from B) and C):B) a further cold flow improver,C) an organic solvent,which comprises mixing cold flow improver and optionally solvent by means of a static mixer, the temperature of the additive mixture at the outlet of the static mixer being from 0° C. to 100° C.
