Abstract:
The invention provides dispersions comprising
I) at least one oil-soluble polymer effective as a cold flow improver for mineral oils,
II) at least one organic, water-immiscible solvent,
III) a dispersant comprising, based on the total amount of dispersant,
a) 10-90% by weight of a salt of an ethercarboxylic acid and
b) 90-10% by weight of a nonionic surfactant,
IV) water and
V) at least one organic, water-miscible solvent.
