CA 2320436

A polyethylene produced by the homopolymerisation of ethylene or copolymerisation of ethylene with a-olefins in the presence of a catalyst, characterized in that the fraction of low molecular weight polymers having MW<5000 g/mole is lower than 12 % by weight of the produced polymer, and that the produced polyethylene has a measured melt strength expressed by a haul-off (HO) value satisfying the expression: HO > K1 . .etaØ05 + K2, wherein K1 is 9.10-5 and K2 is 0.4.

La présente invention concerne un polyéthylène obtenu par homopolymérisation d'éthylène ou par copolymérisation d'éthylène avec des alpha -oléfines en présence d'un catalyseur, caractérisé en ceci que la fraction de polymères à faible poids moléculaire (<5000 g/mole) est inférieure à 12 % en poids du polymère produit, et que ledit polyéthylène possède une résistance à l'état fondu exprimée par une valeur de tirage conforme à la formule suivante: HO > K1. eta 0,05 + K2, où K1est 9.10<-5> et K2 est 0,4.
