Abstract
Polymeric composition containing: a) 100 parts by weight of a random copolymer of propylene and ethylene containing less than 6 weight % of ethylene, b) 0.1 to 4 parts by weight of an elastomeric block copolymer having at least one polymeric block containing predominantly polymerized monovinyl aromatic compound and at least one polymeric block containing predominantly polymerized conjugated diene, and c) 12 to 20 parts by weight of an elastic metallocene polyolefin. Use of said composition for the manufacture of shaped objects and objects so obtained.
