Patent number: 7335716Abstract: An ethylene (co)polymer of the present invention is a (co)polymer with excellent moldability and mechanical properties and either an ethylene homopolymer or a copolymer of ethylene and an ?-olefin of 4 to 20 carbon atoms. The (co)polymer has methyl branches measured by 13C-NMR less than 0.1 in number per 1,000 carbon atoms and Mw/Mn measured by GPC not lower than 1.8 and lower than 4.5. The (co)polymer is either an ethylene homopolymer or a copolymer of ethylene and an ?-olefin of 3 to 20 carbon atoms. The melt tension (MT) and the swell ratio (SR) satisfy the relation; log(MT)>12.9?7.15×SR; and the intrinsic viscosity ([?]) and the melt flow rate (MFR) satisfy the relation; [?]>1.85×MFR?0.192 in the case of MFR?1 and the relation; [?]>1.85×MFR?0.213 in the case of MFR?1. Such an ethylene (co)polymer can be usable for various molding applications and especially suitable for pipes.Type: GrantFiled: June 16, 2000Date of Patent: February 26, 2008Assignee: Mitsui Chemicals, Inc.Inventors: Mamoru Takahashi, Tetsuji Kasai, Junji Saito, Naoto Matsukawa, Kazutaka Tsuru, Makoto Mitani, Terunori Fujita, Shiro Otsuzuki, Tetsuhiro Matsumoto, Toshiyuki Tsutsui
