Research Of Environmentally Safe Material Based On Polyeslesulphone

Among all polymeric materials, a special place is occupied by structural polymers, which are capable of withstanding various operating conditions and exhibit increased thermal resistance.One of these classes of promising polymers are aromatic polyethersulfones characterized by a complex of valuable physical and mechanical properties.Synthesis of polyethersulfones with terephthaloyl-di (p-hydroxybenzoic) acid groups in the main macromolecular chain has been carried out.For the synthesis of these polyethers, the method of acceptor-catalytic polycondensation was employed.For all synthesized polyethersulfones, such mechanical characteristics as tensile strength and breaking strain, which characterize the behavior of polymer under high loads applied, were investigated.The obtained polyethersulfones with phydroxybenzoic acid units exhibit high thermal and mechanical characteristics.Polyethersulfones can be used as structural polymers.The synthesized polyethersulfones with p-hydroxybenzoic acid units exhibit high thermal and mechanical characteristics, tensile strength and breaking strain, and high glass transition temperature.This suggests that some of the proposed polyethers may be industrially promising engineering polymeric materials.
