| Zusammenfassung: | A mouldable composition comprises a polymer of a mono-olefin and comminuted petroleum coke, at least 60% by weight of the coke particles having average particle diameters in the range from 0.75 to 50 microns. The preferred polymers are those derived from ethylene, propylene and butylene, and the coke is preferably present in from 100 to 500 parts per 100 of polymer. The compositions find application as extruded pipe. Specifications 752,400, 799,392 and 810,023 are referred to. |
