The waxes for use in mfr. of internal or external lubricants, in the rubber industry and in prodn. of inks, paints, lacquers and pencils, are made by de-polymerisation of olefinic polymers or copolymers at 200-500 deg. C with shear forces in the molten mass of 0.5 kg/m. in an induction-heated tubular reactor equipped with agitation to produce a high shear coefft. The polymer is polyethylene, polypropylene, or copolymer or mixts. of these.
