Polymerization of heterocyclic monomers is known to lead to the formation of polymers possessing complex of predictable practically useful properties, in particular , thermoplastic and heat-resistant ones. As objects of research we used heterocyclic polyamide synthesized by polycondensation of ethyl ester of ethylenetetracarboxylic acid with polyfunctional diamine. For our research the method of low-temperature polycondensation which began to be applied recently was the most suitable method for obtaining polyamides. The advantage of this method is reducing the duration of the polycondensation and the possibility of obtaining products of high molar mass. Low-temperature polycondensation process is also used for obtaining unstable at the melting point polyamides with aromatic nuclei. [ABSTRACT FROM AUTHOR] |
