Abstract
This invention relates to a poly(azomethine-ester) having a repeating structural unit of the following formula [1] ##STR1## wherein Ar.sub.1 and Ar.sub.2, which may be the same or different, are selected from phenylene or divalent organic radicals terminated with an aromatic ring on the both ends of the each radical, respectively, and R.sub.1 is selected from hydrogen, alkyl, alkoxy or aryl radical. The poly(azomethine-esters) according to the present invention are soluble in common organic solvents and have film-forming ability and heat-resistance.
