Abstract

Ethylene--octene copolymer characterized by a density in the range of 850 kg/mto 930 kg/mmeasured according to ISO 1183-187, a melt flow rate MFR2 (190° C., 2.16 kg) in the range of from 0.3 g/10 min to 100 g/10 min measured according to ISO 1133, a MFR/MFRof from 5.0 to 15.0, a Mw/Mn of from 2.0 to 5.0, 1.0 to below 20 vinyl unsaturation units/100,000 C atoms, more than 5.0 to 35 vinylidene unsaturation units/100,000 C atoms, more than 5.0 to 30 vinylene unsaturation units/100,000 C atoms, more than 15.0 to 60 trisubstituted unsaturation units/100,000 C atoms, 26 to 150 total unsaturation units/100,000 C atoms, wherein the total unsaturation units/100,000 C atoms is the sum of vinyl unsaturation units/100,000 C atoms, vinylidene unsaturation units/100,000 C atoms, vinylene unsaturation units/100,000 C atoms and trisubstituted unsaturation units/100,000 C atoms, an unsaturation degree for unsaturation types e) to h) according to formula (I) wherein a vinyl unsaturation degree is in the range of from 5.0 to 15.0%, a vinylene unsaturation degree is in the range of from 20.0 to 30.0%, and wherein the sum of the vinyl unsaturation degree and vinylidene unsaturation degree is at least 30.0% and up to 50.0%.
