The formation of dissipative structures in polymers as a model of synergy

Abstract

Abstract. Synergetic is an interdisciplinary area and describes the emergence of various kinds of structures, using the representation of the natural sciences. In this paper we studied the conditions for the appearance of thermodynamically stable amorphous-crystalline supramolecular structures on the basis of practical importance for the production of heat-resistant high-strength polymer fibers semi-rigid systems. It is found that in the process of structure formation in the coagulation of the polymer from solutions having supramolecular structures area a definite geometric shape and dimensions. Pattern formation in such systems can simulate the processes studied synergy. This is occurring in the process of self-organization of dissipative structures, transitions from one structure to another. This most discussed matter of selforganization on the "optical" scale level, are observed spherulites have a "correct" form and certain geometric dimensions comparable to the wavelength of visible light. Previously, this polymer does not crystallize at all considered. It is shown that for the study of supramolecular structures are the most convenient and informative experimental approaches are polarization-optical methods, which are directly "tuned" to the optical anisotropy of the structure and morphology. The great advantage of these methods is also possible to study the kinetics of structure formation processes without interfering the system under study.

The Liquid Crystal State Poliamidbenzimidazola Solutions in Sulfuric Acid

“…2, H v , V v , c). This intensity distribution can be called molecular groups in a cholesteric state [3].…”

“…Fibers of this polymer is formed from a liquid crystal (LC) solutions in concentrated sulfuric acid. Less studied, but no less practical significance is poliamidbenzimidazol (PABI), which is also derived from the LC in H 2 SO 4 solutions [3]. Research polyheteroarylenes LC status is of great scientific and practical importance, as it allows to establish the general laws of phase transitions in polymers and to use the transition phenomenon in the mesophase to obtain highstrength fibers and films.…”
