    Abstract: A copolymer of ethylene, a catalyst system suitable to prepare the copolymer, and a process to prepare such copolymer are described. The copolymer comprises from 60 to 80% by weight of ethylene and from 20 to 40% by weight of at least one first α-olefin comonomer having n carbon atoms and at least one second α-olefin comonomer having (n-1) carbon atoms, n being from 4 to 13, has a polydispersity M w /M n equal to or lower than 3.5, and a density from 0.855 to 0.880 g/cm 3 . The copolymer is obtained by subjecting ethylene and said at least one first α-olefin comonomer to a polymerization stage in the presence of a catalyst system capable of forming a copolymer of ethylene and said at least one first α-olefin comonomer having n carbon atoms, while forming the second α-olefin comonomer having (n-1) carbon atoms.

    Abstract: The invention refers to a process for preparing a supported catalyst system for the polymerization of olefins comprising at least one active catalyst component on a support, the process comprising A) impregnating a dry porous support component with a mixture comprising at least one precatalyst, at least one cocatalyst, and a first solvent, such that the total volume of the mixture is from 0.8 to 2.0 times the total pore volume of the support component, and B) thereafter, adding a second solvent in an amount of more than 1.5 times the total pore volume of the support component. The invention refers further to a catalyst system made by this process and the use of this catalyst system for polymerization or copolymerization of olefins.
