| description | According to one embodiment, a process for producing unimodal ethylene/α-olefin copolymer, the process comprising contacting ethylene and, optionally, one or more (C3-C12)α-olefin comonomers with a catalyst system in a gas-phase polymerization reactor, wherein the catalyst system comprises a chromium-based catalyst; wherein the unimodal ethylene copolymer comprises: a density from 0.942 g/cm3 to 0.950 g/cm3 according to ASTM D792-13; a flow index (I21) from 5.5 to 7.5 dg/min, when measured according to ASTM D1238 at 190° C. and a 21.6 kg load; a strain hardening modulus of 40 to 50 MPa; and a molecular weight distribution (MWD) as determined by a conventional gel permeation chromatography method or absolute gel permeation chromatography. |
