Heteroaromatic polymers are considered to be high performance organic materials due to their unique and highly attractive properties, including outstanding thermal and mechanical resistance, that arise from their aromatic structure and strong interactions

A new phosphorus-containing poly(ester imide) was prepared by polycondensation reaction of a diamine containing a phthalonitrile unit, namely 4,4′-diamino-4′-(3,4-dicyanophenoxy)triphenylmethane, with an aromatic dianhydride having preformed ester groups, namely 1,4-[2-(6-oxido-6H- dibenzoxaphosphorin-6-yl)]-naphthalene-bis(trimellitate) dianhydride. This polymer was easily soluble in polar aprotic solvents such as N-methyl-2-pyrrolidinone, N,N-dimethylacetamide, N,N-dimethylformamide or dimethyl sulfoxide. The poly(ester imide) showed high thermal oxidative stability, the decomposition temperature being above 360°C, and high transition temperature, around 252°C. The thermal decomposition behavior was studied using thermogravimetric analysis in air, at several heating rates between 4 and 19°C/min. The kinetic processing of the data was carried out using ASTM-E1641 method.
