Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The presented monography deals with the very interesting class of polymers - aromatic polyesters. Polymers of this class are characterized by especially high heat- and thermal- stability. Often the melting points of these polymers are higher than their destruction points and makes their thermal processing into different items difficult. Their processing from the solutions of the polymers is mostly limited due to their limited solubility in the solvents. Therefore, the polymers that are simultaneously characterized by good solubility and high thermal stability have special practical importance in different fields of technologies. Such polymers are card type polymers in the macromolecules of which a carbon atom simultaneously belongs both to the main polymeric chain and in the structure of the substituted group. Such polymers appeared to have special properties good solubility and high thermal stability. The present monograph is dedicated to the synthesis and study of the norbornane type card group containing polymers. 108 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The unique properties of epoxy polymers have led to their wide application in various fields of modern technology. The properties of epoxy polymers, depending on the requirements imposed on them, can be widely varied by using various initial components, hardeners, fillers for their synthesis. The scientific novelty of the work consisted in the synthesis of a number of new, undescribed in the literature glycidyl ethers and epoxy polymers based on them, in the study of the kinetic laws of the formation of epoxy polymers based on polycyclic bisphenols of the norbornane type. New hardeners are proposed: acid anhydrides with norbornane groups, silicon-containing diamines, novolacic oligomers. For the successful synthesis of epoxy 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. The resulting epoxy polymers can practically be used as binders of self-lubricating antifriction plastics, high-temperature dielectrics, fiberglass, adhesives, varnishes with increased thermal and heat resistance and good physical and mechanical properties. 140 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -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. 140 pp. Englisch.…
