Abstract: Hollow articles are made from stabilizer-free high-density polyethylene, e.g. by blow moulding a fuel container in the absence of oxygen. The absence of stabilizers, e.g. UV or heat stabilizers, is said to improve the barrier effect, or resistance to fuel permeability, long term, to which end the container may also be conventionally treated with a reactive gas, e.g. containing fluorine.

Abstract: A process for the preparation of finely divided polyolefin molding materials from 100 parts by weight of polyolefin and from 1 to 30 parts by weight of a conductive carbon black, with or without other additives, wherein the mixture of polyolefin powder and carbon black is compounded, in a first stage, until the crystallite melting point of the polyolefin is reached, and is then brought, in a second stage, to a temperature which is from 3 DEG to 40 DEG C. above the said crystallite melting point, after which the mixture is discharged from the mixer within from 0.5 to 30 seconds and is cooled within 120 seconds.
