Abstract
Polymers containing 3,3′-dioxo-5,5′-biindol-2,2′-diyl units were synthesized by high temperature polycondensation of 4,4′-diaminobiphenyl-3,3′-dicarboxylic acid (1) with ethylene dichloride and dibromide, 4-chloromethylbenzyl chloride and bromide, 4-chloromethyl-2,5-dimethylbenzyl chloride and bis(4-chloromethylphenyl) ether under different experimental conditions. These resulting polymers 5a–d were characterized by viscometric and IR Spectral studies and by TG in air. Kinetic parameters of their thermal degradation were evaluated.
