Abstract

Process for the production of an ethylene copolymer, characterized in that it comprises copolymerizing ethylene and a comonomer which is at least one mono-alpha-olefin, of which at least 50 mol% is the comonomer having 5 or more carbon atoms, in the presence of a transition metal catalyst for the polymerization of olefins; and separating a polymeric product having an annealed density of the order of 918 to 940 kg/m3, an apparent viscosity, measured at a temperature of 200ºC and a shear stress of 100 sec-1, of the order of 0.5 x 103 to 3.0 x 103 nsm-2 and a viscosity, measured at a temperature of 200ºC and an effort of 103 n/m2, of at least 2ae (1.6a x 103) and not higher than 1,000a, where a is the apparent viscosity at 200ºC and a shear stress of 100 sec-1.
