Synthesis Methods and Properties of Polyazoles

Abstract

Abstract There is an acute demand for thermally and heat-stable materials in modern technology. Of great interest are also polymers resistant to chemicals, particularly to oils, organic solvents, and mineral acids, as well as those possessing stability to light and radiation, and electroinsulating, semiconductive, and catalytic properties. These polymeric materials must have good mechanical properties and be suitable for existing industrial processing and synthesis techniques if they are to be useful technologically. Polymers containing various heterocycles in the chain attract, therefore, the increasing attention of polymer chemists, as it is known that many 5and 6 membered heterocycles are stable to high temperatures and have some specific useful properties. Of the heterocycle-containing polymers, polyazoles, the polymers with azole cycles in the chains, are exceptionally interesting and have been studied adequately. Some polyazoles are described in a number of reviews and monographs dealing mainly with the synthesis of thermally stable polymers [1–101].
