Patent ID: 6878790

Claim:
A polymeric material comprising substantially linear polyolefin molecules comprising C 3 -C 20 monomers, said linear polyolefin molecules being characterized by a total pentad area and characterized in that the relative content of [mmmm] of said polyolefin is between 10% and 60% of said total pentad area, the weight average molecular weight of said linear polyolefin molecules is at least 1000 kg/mol, and said polymeric material has a ratio k of at least 0.05; wherein k is defined as k = [ mrrm ] - [ m ] 2 ⁢ ( 1 - [ m ] ) 2 [ m ] ⁢ ( 1 - [ m ] ) - [ m ] 2 ⁢ ( 1 - [ m ] ) 2 and further wherein the relative content of [mmmm] of said linear polyolefin is between 2.5% and 7% of said total pentad area.
