Patent number: 8722832Abstract: 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 ?-olefin comonomer having n carbon atoms and at least one second ?-olefin comonomer having (n?1) carbon atoms, n being from 4 to 13, has a polydispersity Mw/Mn equal to or lower than 3.5, and a density from 0.855 to 0.880 g/cm3. The copolymer is obtained by subjecting ethylene and said at least one first ?-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 ?-olefin comonomer having n carbon atoms, while forming the second ?-olefin comonomer having (n?1) carbon atoms.Type: GrantFiled: November 27, 2008Date of Patent: May 13, 2014Assignee: Basell Polyolefine GmbHInventors: Fabiana Fantinel, Shahram Mihan, Isabella Camurati
