Abstract
Based on theoretical and experimental data, a correlation was demonstrated between the stability factor of concentrated solutions, difference in the glass transition temperatures of the components of the mixtures, and reaction parameter between polymers. It was found that the polymer reaction parameter can be used as the criterion for selecting the optimum concentration of the second component in fabrication of fibers from polymer blends. The “doping” role of small amounts of polymer additives in PAN, which causes an extreme increase in the physicomechanical and especially the fatigue properties of fibers from polymer blends, was demonstrated.
