EHTLYNEE-OCTENE COPOLYMER HAVING NARROW MOLECULAR WEIGHT DISTRIBUTION AND UNIFORM DISTRIBUTION OF COMONOMERS COPOLYMERIZED WITH ETHYLENE

摘要

PURPOSE: An ethylene-octene copolymer is provided to have uniform distribution of comonomers, and to impart lower density and melting point than same copolymer content.;CONSTITUTION: An ethylene-octene copolymer is manufactured under the presence of a catalyst composition, has density of 0.857 - 0.91 g/cm^3, has molecular weight distribution(Mw/Mn) of 3.5 or less, and A multiply of reactivity(re) of the copolymer to an ethylene catalyst, and reactivity of octene to the catalyst is 0.5-0.8. The density of the ethylene-octene copolymer and octene content(α, mol%) in the ethylene-octene copolymer satisfies formula 1: 0.9190 - 0.0043α density 0.9205 - 0.0040α. The catalyst composition comprises a metallocene catalyst.;COPYRIGHT KIPO 2012
