    Abstract: Molten polyolefins having a molecular weight of between 1,000 and 50,000 are oxidized with oxygen or oxygen-containing gas under increased pressure and at a temperature between 130 DEG and 250 DEG C. until 0.5 to 25 kg of oxygen has been absorbed for each 100 kg of polyolefin and the oxidation is carried out with intense agitation with an agitator output of from 1 to 15 kilowatts per 100 kg of polyolefin. Polyolefins exemplified are polyethylene, polypropylene, and a copolymer of ethylene and carbon monoxide containing between 1 and 3 carbonyl groups per 50 ethylene groups. The materials may be made by thermally degrading high molecular weight polyolefins. The products are easily emulsifiable waxes.
