Resumo
In this work, the synthesis of aromatic oligosulfones of various structures and degrees of poly- condensation was studied in order to obtain block copolyesters with high molecular weight, improved heat- resistant characteristics and high physical and mechanical properties. It was shown that with an increase in the degree of condensation of oligosulfones, an increase in softening temperatures is observed, at which the percent- age of hydroxyl groups simultaneously decreases. To determine the presence of hydroxyl groups at the ends of oligosulfones in accordance with the expected structure, as well as their activity, test syntheses were carried out on the obtained oligosulfones. Some results and elemental analysis data are presented, which, together with IR spectroscopy, confirm the structure and composition of the synthesized oligosulfones. Block copolyesters with high values of reduced viscosity were obtained by the method of acceptor-catalytic polycondensation using phthalic acid dichlorides.
