A PROCESS FOR HOMOGENIZING AND PELLETIZING A POLYETHYLENE COMPOSITION

摘要

A process for homogenizing and pelletizing a polyethylene composition comprising the steps of a) providing a polyethylene composition having a density of from 0.90 g/cm3 to 0.97 g/cm3 and a melt flow rate MFR21.6 at 190°C under a load of 21.6 kg of from 1 g/10 min to 80 g/10 min; b) melting the polyethylene composition; c) passing the melt through a combination of screens consisting of screens having a mesh opening of at least 205 µ?t? and comprising at least two screens having a mesh opening of from 205 µ?t? to 350 µ?t?; and e) pelletizing the molten polyethylene composition, the use of a polyethylene composition obtained by such a process for the preparation of films, fibers, pipes, blow-molded articles, injection-molded articles, compression-molded articles or rotomolded articles and films, fibers, pipes, blow-molded articles, injection-molded articles, compression-molded articles or rotomolded articles prepared from a polyethylene composition obtained by such a process.
