A number of dianhydrides containing ester groups have been used for the synthesis of poly(ester imide)s. Most of them are bistrimellitates which are synthesized by condensation of diacetylbisphenols (R = arylene) with two moles of trimellitic anhydride (4-carboxyphthalic anhydride), or by condensation of glycols (R = alkylene) with two moles of alkyltrimellitate by ester interchange in the melt [4,147,148].
