Title

Polyamic Acid Esters Characterized by Thermogravimetric Analysis

Abstract

Novel alkyl esters of oxydianiline/pyromellitic dianhydride polyamic acid have been synthesized using a coupling agent reaction. These alkyl esters were prepared as the pure meta and para polymers. The cure behavior of these polymers was studied using thennogravimetric analysis and compared to that of both the parent polyamic acid and its methyl ester. Curing was found to be similar to that of the parent ODA-PMDA, but the data shows that the isomeric esters have a lower onset of reaction temperature as well as a narrower reaction range than the methyl ester. It was also shown than differences between theoretical and experimental weight loss are significantly larger for ODA-PMDA polyamic acid than for either the isomeric esters or the methyl ester.
