Abstract:
1. A copolymer comprising ethylene and from 0.5 to 25 mol % of C 3 to C 20 olefin comonomer, said copolymer having: 1) a ratio of Ultimate Tensile Stress to Tensile Stress at 100% elongation of 2.5 or more; 2) a ratio of Ultimate Tensile Stress to Tensile Stress at 300% elongation of 2.4 or more; 3) a ratio of Ultimate Tensile Stress to Tensile Stress at the primary yield point of 2.9 or more; 4) a density of 0.910 g/cm 3 or more; 5) a 1% secant modulus of 30 to 100 MPa; 6) a Tensile Stress of Y MPa or more, where Y=(0.0532)*Z−8.6733 and Z is the percent strain and is a number from 500 to 2000; and 7) a 1% secant modulus of 40 to 100 MPa.
