Beschreibung
Zusammenfassung:	Segmented polyolefins, which are produced by the reaction of mixtures of powdery polyolefins and polyolefin granulates with unsaturated monomers in the presence of thermally decomposing free radical-forming agents in continuous mixers in two consecutive reaction steps in the solid phase, a reaction step in a solid phase/melt transition phase and a melt homogenizing step, have a high strength and tenacity. The segmented polyolefins, as well as mixtures with conventional polyolefins, are suitable for the production of films, sheets, fibers, panels, coatings, pipes, hollow objects and foams.
