It was found that at a critical concentration of a specific beta-nucleant of 0.03 wt % the content of the beta-modification virtually reaches a saturation level. The long period passes through a distinct maximum at the same nucleant concentration. This singularity in structure remarkably correlates with a minimum of the yield stress and maxima of strain at break and fracture toughness.
