Abstract
A copolymer of ethylene and an alpha-olefin, said copolymer having a (a) density>0.930 g/cm, (b) melt index (g/10 min)>4, (c) molecular weight distribution (MWD)>3.0, and (d) FNCT>250 hours, and is described suitable for use in rotomolding applications. In particular the novel copolymers result in improved impact strength, improved permeation resistance and improved environmental stress crack resistance and may suitably be prepared by use of metallocene catalysts.
