ABSTRACT:
A process for the preparation of water-emulsifiable polyethylene by oxidizing high density polyethylene, at below the softening point of the polyethylene, in the presence of oxygen, wherein the oxidation is carried out in a fluidized bed reactor, using a polyethylene which beforehand has been heated, with exclusion of oxygen, in the presence of a compound which forms free radicals.
