Abstract

The present disclosure relates to a polyolefin composition comprising: A) from 99.5% to 60% by weight of a recyclate polyolefin component containing not less than 80% by weight of a waste material selected from polyethylene, polypropylene or their mixtures; B) from 0.5% to 40% by weight of an ethylene copolymer having: 1) a 1-butene from 15% to 45% by weight; 2) density from 0.840 to 0.910 g/cm<3>; 3) Melt Flow Rate E from 0.1 to 15 g/10 min., preferably from 0.3 to 12 g/10 min., measured according to ISO 1133-1 2012-03 at 190 °C, with a load of 2.16 kg; 4) product r1·r2 of the reactivity ratios obtained from <13>C NMR triad distribution, from 0.55 to 0.95, where r1 is the reactivity ratio of ethylene to 1-butene and r2 is the reactivity ratio of 1-butene to ethylene.
