Abstract: The invention relates to an improved process, wherein polyolefins are freed from saturated liquid residual hydrocarbons with the aid of water and steam. The improvement comprises A. introducing the hydrocarbon-containing polyolefin into an aqueous emulsifier-containing solution having a surface tension at 20 DEG C. of about 50 to 60 dynes/cm with respect to air; stirring the resulting mixture and converting it to a homogeneous dispersion, the aqueous dispersion containing about 10 to 40 weight % of the polyolefin; B. introducing the dispersion into the upper portion of a column provided with 5 to 30 sieve plates and overflow weirs and contacting the dispersion in countercurrent fashion with steam of about 100 DEG to 120 DEG C.
