Abstract
A polyolefin has 1) a density in the range of 0.93 to 0.97 g/cm3, 2) a BOCD (Broad Orthogonal Co-monomer Distribution) index defined by a given equation in the range of 1 to 5, and 3) a molecular weight distribution (weight average molecular weight/number average molecular weight) in the range of 4 to 10. A supported hybrid metallocene catalyst comprises a first metallocene compound represented by a first given formulae, a second metallocene compound represented by one of three given formulae, and a support.
