Abstract
The invention is directed to HDPE having a quotient of melt strength according to ISO 16790:2005 and apparent viscosity according to ISO 11443:2014 (melt strength/apparent viscosity)>2 cN/k·Pa·s and ≤30 cN/k·Pa·s. In a preferred embodiment, HDPE with an Ml in the range between ≥0.1 and ≤10 a density in the range between ≥935 and ≤970 kg/ma gel fraction less than 5% and an elasticity (ratio of G'/G″ at 0.1 rad/sec) between ≥0.6 and ≤10 is obtained by chain branching HDPE with an Ml in the range between ≥10 and ≤100 a density in the range between ≥935 and ≤970 kg/mand an elasticity (ratio of G′/G″ at 0.1 rad/sec) between ≥0.01 and ≤0.2.
