摘要: Abstract The paper relates to a general structural model for aromatic polymers. It is proposed that phenylene and planar heterocyclic groupings in these polymers are strictly parallel arrangement (in crystalline regions) relative one another, practically amorphous regions. main feature of the systems question seen strong intermolecular interactions restricting torsional oscillations groups hindering their transition free rotation. properties behaviour depend lesser extent on rigidity individual chains more strongly hindered macromolecular ensembles. appropriate calculations carried out aling with an analysis concrete systems.
