Aromatic polyesters based on the norbornane type bisphenols

At the turn of the last and new centuries, the development of cutting-edge equipment greatly increased the requirements for new materials that would have the ability to work in extreme conditions. This gave a powerful impetus to the development of polymer chemistry, especially research in the field of polycondensation.Among high-temperature and heat-resistant polymers, complex aromatic polyesters of the card type are of particular interest, in particular polyarylates, which contain side cyclic substituents in a repeating ring of polymers, one of the atoms of which is simultaneously included both in the substitution and in the main polymer chain. The presence of such groups gives polymers specific properties. They are simultaneously characterized by both good solubility in organic solvents and high thermal parameters, which allows them to be processed from solutions.For the successful synthesis of card-type polymers, it was necessary to study the mechanism and patterns of their formation, which was successfully implemented in this work and the results of the study are fully presented in the monograph.
