Beschreibung
Zusammenfassung:	A polyetherimide ester polymer comprised of the reaction products of: (i) a diol component comprising at least one low molecular weight diol and at least one high molecular weight diol; (ii) at least one dicarboxylic acid or an ester forming reactive derivative thereof; and (ii) a set of reactants selected from (a) (1) at least one high molecular weight poly(oxy alkylene)diamine, and (2) at least one tricarboxylic acid or its derivative, or (b) at least one high molecular weight polyoxyalkylene diimide diacid. The polymer of this invention exhibits improved flexibility; and the diol component (i) contains an amount of high molecular weight diol at least effective to improve the flexibility of the polymer.
