Abstract (en)

[origin: ES470543A1] Process for the extrusion, followed by cooling with water, of compositions based on alpha-olefin polymers. The composition being extruded comprises a phenolic anti-oxidizing agent, an organic phosphite, and a carbonate of an alkaline-earth metal. The process permits fabricating films, filaments and tubes.
