Abstract
A wax-containing crude oil or a wax-containing fuel oil, in
particular a wax-containing residual fuel oil, comprising a
small amount of a polymer having predominantly aliphatic
hydrocarbon side chains of at least 14 carbon atoms, charac
terized in that the polymer has a branched backbone. This
polymer shows an excellent pour point depression at low
concentrations.
