Beschreibung
Zusammenfassung:	The invention relates to a polymer composition with a high filler content on the basis of a crystalline propylene polymer and talc that is suitable for the manufacture of moulded articles. According to the invention the polymer composition contains 30-68% by weight of a propylene-ethylene block copolymer with 2-30% by weight of ethylene units, 30-60% by weight of talc and 2-20% by weight of a rubbery ethylen-propylene copolymer, and contains preferably also 1-10% by weight of polyethylene with a density of at least 0.94 g/cm . The polymer composition according to the invention shows at a high filler content with the corresponding advantages a high degree of impact strength at sufficient rigidity.
