NEW POLYESTERPHTHALIMIDES BASED ON BIS(p-AMINOPYHENOXY) ARYLENES AND BIS(ETHEROPHTALIC ANHYDRIDES)

A study has been conducted in the synthesis of soluble, thermo- and flame-resistant polyethyrphthalimides based on bis(p-aminophenoxy)ariylenes and bis(phthalic anhydrides). The main ways of obtaining polyethyrphthalimides are considered – by the interaction of bis(p-aminophenoxy) ariylenes with bis(etherophthalic anhydrides) using a polycyclocondensation reaction. The effectiveness of the use of bis(p-aminophenoxy) is shownariylenes containing two simple ether bonds in the initial ones, it was found that the obtained polymers have sufficiently large temperature ranges of softening and active destruction. The interrelation of their structure and properties has been established. The influence of dichloroethylene, carbonyl and simple ether groups between the phenyl nuclei of central fragments of macromolecules on the solubility, thermal and strength properties of synthesized polymers has been studied.
