Synthesis and properties of a new polyesterimide

TLDR
A polyesterimide was prepared by reacting 4,4′-diaminodiphenylmethane with trimellitic acid anhydride in ethylene glycol, which acts as an esterification reagent as well as a solvent as discussed by the authors.
Abstract
A polyesterimide was prepared by reacting 4,4′-diaminodiphenylmethane with trimellitic acid anhydride in ethylene glycol, which acts as an esterification reagent as well as a solvent. The solution and thermal behaviour, and a few other properties were studied. The polymer was found to be soluble in highly polar solvents. The polymer solution was stable. Thermogravimetric data revealed that the polymer underwent only 10% weight loss in air at 300°C. Ein Polyesterimid wurde durch Reaktion von 4,4′-Diaminodiphenylmethan mit Trimellithsaureanhydrid in Ethylenglykol hergestellt. Letzteres dient sowohl der Veresterung als auch als Losungsmittel. Die Loslichkeit, das thermische Verhalten und einige andere Eigenschaften wurden studiert. Es wurde gefunden, das das Polymere in hochpolaren Losungsmitteln loslich und die Polymerlosung stabil ist. Thermogravimetrische Daten zeigten, das das Polymere bei 300°C in Luft nur 10% Gewichtsverlust erleidet.

Synthesis and properties of new organo-soluble and strictly alternating aromatic poly(ester-imide)s from 3,3-bis[4-(trimellitimidophenoxy)phenyl]phthalide and bisphenols

TL;DR: A series of strictly alternating aromatic poly(ester-imide)s having inherent viscosities of 0.20 - 0.98 dL/g was synthesized by the diphenylchlorophosphate (DPCP) activated direct polycondensation of the preformed imide ring-containing di- acid, 3,3-bis(4-(trimellitimidophenoxy)phenyl)phthalide (I), with various bisphenols in a medium consisting of pyridine and lithium chloride as mentioned in this paper.
