the fully oriented polymer chain and study the importance of molecular weight and
segregated chain-end defects in controlling the fiber ultimate tensile strength. We find
a rather weak dependence of the maximum strength on molecular weight, 0 zz M0.4.
Molecular defects, on the other hand, are found to have a profound effect on fiber
mechanical properties. We show that our model predictions are in good agreement with
available experimental data.
