    摘要： The present invention pertains to a UHMWPE film having a tensile strength of at least 2.0 GPa, a tensile energy to break of at least 30 J/g, an Mw of at least 500 000 gram/mole, and a Mw/Mn ratio of at most 6.
    The film may be manufactured via a process which comprises subjecting a starting UHMWPE with a weight average molecular weight of at least 500 000 gram/mole, an elastic shear modulus determined directly after melting at 160°C of at most 0.9 MPa, and a Mw/Mn ratio of at most 6 to a compacting step and a stretching step under such conditions that at no point during the processing of the polymer its temperature is raised to a value above its melting point.
    The film may be used as starting material in any applications where high tensile strength and high energy to break are important. Suitable applications include ballistic applications, ropes, cables, nets, fabrics, and protective applications.

    摘要： A rope comprising polyethylene elongate elements oriented in the length direction of the rope wherein for at least part of the elongate elements the distance of the element to a central longitudinal rope axis varies over the length of the rope, the polyethylene elongate elements comprising tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt.%. The distance of at least part of the elements to the central longitudinal rope axis varies over the length of the rope between a longitudinal line which is at most 30% from the outside of the rope and a longitudinal line which is at most 30% from the central longitudinal axis of the rope. A rope with these properties, shows a high strength-strength ratio, defined as the ratio between the strength under use conditions and the fresh strength of the rope. A strength-strength ratio of at least 50%, preferably at least 70%, in particular at least 80% can be achieved.
