Process for melt-shaping a polymer composition

摘要

The invention relates to a process for melt-shaping a polymer composition wherein the constituent components for the polymer composition are supplied directly to the shaping device in the form of a mixture of granules on or in which the constituent components are present. The granule mixture contains at least 3 granule fractions containing the matrix polymer that differ in composition. The invention also relates to the granule mixture suitable for the melt- shaping process, the installation for the preparation and the process for preparing the granule mixture. The process results in a greater reproducibility and in articles with improved properties.
