Ethylene and an alpha olefin, METHOD FOR THE PREPARATION OF copolymers, ROTOMODULADO ARTICLE AND USE OF A COPOLYMER PREPARED BY THE USE OF A MONOCICLOPENTADIENIL metallocene catalyst COMPONENT

摘要

A copolymer of ethylene and an alpha olefin, said copolymer having (a) a density 7930 g / cm ^ 3 ^, (b) an index of fusion (g / 10 min) 4, (c) the distribution of the molecular weight (MWD) 3.0, and (d) test of time the total resistance with the notch (FNCT) 250 hours, and is described suitable for The applications of rotomoldagens.In particular, the new copolymers result in a better impact resistance, and resistance to environmental tensofissuarmento and can be properly prepared by the use of metaloceno catalysts.
