摘要： The present invention concerns a multimodal, preferably bimodal, polyethylene (PE) composition comprising a base resin which comprises (A) a first ethylene homo- or copolymer fraction, and (B) a second ethylene homo- or copolymer fraction, wherein (i) fraction (A) has a lower weight average molecular weight than fraction (B), (ii) the base resin has an MFRS of at least 0.01 g/10 min and (iii) the base resin is obtainable by polymerising ethylene and optionally at least one comonomer in the presence of a catalyst having an overall activity of at least 30 kg polymer per g catalyst. Furthermore, the present invention relates to a process for the production of such a composition as well as to the use of such a composition for the production of articles.
