Abstract

Crystal length determinations have been undertaken on ultrahigh‐modulus linear polyethylene fibers by dark‐field electron microscopy. There is good agreement between the results and those obtained from wide‐angle x‐ray diffraction line broadening. The crystal length distributions from the dark‐field microscopy are also consistent with those determined by nitric acid etching. The significance of the present results is considered in the light of recent proposals for the structure of these materials and the achievement of high modulus.
