  • Ethylene (co) polymers, and laminate and hollow molding made by using the same
    Patent number: 6716385
    Abstract: Ethylene (co)polymers each having specified values of (a) density, (b) molecular weight distribution (Mw/Mn), (c) relationship between die swell (DS) and shear rate (&ggr;) in a region of shear rate ({dot over (&ggr;)}), (d) relationship between stress (&sgr;) and maximum stress (&sgr; max) in a stress-strain curve in uniaxial stretching, (e) the ratio of sample diameter to initial sample diameter and the time for sample breakage during uniaxial stretching under a constant tension, blow molding process in which the thickness of a parison is adjusted by using the said ethylene (co)polymer, and the method of improving fire resistance in moldings, laminates and hollow moldings made by using the same.
