Abstract: Prodn. of oxidised polyethylenes (I) with acid number of 10-40 is carried out by oxidising finely-divided HDPE below its softening point and above 100 deg.C with air and/or O2 contg. min. 100 mg O3/kg HDPE-h. Oxidn. is carried out in a paddle drier and the oxidn. gas is passed into the empty gas space over the HDPE. Pref., the temp. in the paddle drier is continuously adjusted to 1-2 deg.C below the softening of the HDPE.

Abstract: Oxidized polyethylenes useful as water-emulsifiable waxes and as lubricants in the extrusion of polyvinyl chloride are prepared by oxidizing finely divided polyethylene of high density at elevated temperatures with an oxidation gas of air and/or oxygen, the oxidation gas supplied per hour containing not less the 100 mg of ozone per kilogram of polyethylene, by performing the oxidiation in a paddle dryer and passing the oxidation gas into the free gas space above the polyethylene, the temperature in the paddly dryer preferably being continuously adjusted to from 1 DEG to 2 DEG C. below the softening point of the polyethylene.
