    摘要: The present invention relates to a method of producing a high strength and high modulus elongated product comprising the steps of (a) making a composition comprising a semi-crystalline polymer and carbon nanotubes, (b) extruding said composition into an elongated product, and (c) stretching the product below the melting point of the polymer, wherein in step (a) the composition is a colloidal dispersion of nanotubes in a solution of the polymer. The advantages of the invention include production of elongated products, like fibres with higher tensile properties, especially strength, with a lower concentration of nanotubes than with a known method.
    The invention also concerns a high strength elongated product containing nanotubes obtainable by the method according to the invention, especially a polyolefin fibre containing nanotubes having a tensile strength of higher than 3.0 GPa. The invention also relates to a process for making composite articles wherein high strength elongated products, preferably fibres, according to the invention are used and to anti-ballistic composites comprising said products.
