Abstract: Fibrous polyolefines purified by oxidativethermal degradation methods as described in Specification 883,804 and suspended in saturated hydrocarbons with/without water, are worked up by screening off the bulk of the saturated hydrocarbon, followed by squeezing the screened polyolefin mass and vacuum extruding the resulting polyolefin cake, optionally degrading to an intrinsic viscosity above 0,5, and finally granulating in the usual way. The polymer may be a polymer or copolymer of ethylene, propylene and/or butene. In examples sieve drums, rollers, oil presses, screen and filter belts and fruit presses are used in effecting the method specified.
