Abstract
A novel PE material is devised showing excellent mechanical/optical properties and process ability, e.g. for film extrusion. The polyethylene of the invention is produced in one single e.g. gas phase reactor.
Claims51
A polyethylene comprising;
- i. 70% to 95% by weight, as a first polymeric component, of a copolymer of ethylene with at least one C3-C20-α-olefine-comonomer which copolymer has a MWD<5, a CDBI>60% and a high load melt index (@21.6 kg, 190° C.) measured according to ISO1133:2005 of from 10 to 100 g/10 min., and
- ii. 5 to 30% by weight, as a second polymeric component, of a substantially homopolymeric polyethylene having a MWD>10, a CDBI>80% and a high load melt index (@21.6 kg, 190° C.) measured according to ISO1133:2005 of from 0.2 to 20 g/10 min,
- wherein the polyethylene is multimodal in comonomer distribution analysis.
