Polyolefin-Filme. |
摘要 |
<p>Disclosed are films or sheets comprising an olefin polymer composition which is comprised of (a) from about 10 to 50 parts of a propylene homopolymer having an isotactic index greater than 80, or a copolymer of propylene with ethylene and/or an another alpha-olefin, containing over 80% propylene and having an isotactic index greater than 80; (b) from about 5 to 20 parts of a semi-crystalline copolymer fraction, which copolymer is insoluble in xylene at room or ambient temperature; and c) from about 40 to 80 parts of a copolymer fraction of ethylene with propylene and/or another alpha-olefin, and optionally with minor amounts of a diene, said copolymer fraction containing less than 40% ethylene and/or other alpha-olefin, being soluble in xylene at room temperature, and having an intrinsic viscosity from 1.5 to 4 dl/g. Coextruded films or sheets and laminates wherein at least one layer is a film or sheet as described above, and films or sheets of blends of the olefin polymer composition and another olefin polymer are also disclosed.</p> |
