Abstract
A polyetherimide ester composition comprising the reaction products of: PA1 (i) at least one diol; PA1 (ii) at least one dicarboxylic acid or an ester forming reactive derivative thereof; and PA1 (iii) a set of reactants selected from PA2 (A) (1) a diamine mixture of at least one high molecular weight poly(oxy alkylene) diamine and at least one low molecular weight hydrocarbylene diamine, and (2) at least one tricarboxylic acid or its derivative, or PA2 (B) a mixture of at least one high molecular weight polyoxyalkylene diimide diacid and at least one low molecular weight hydrocarbylene diimide diacid. These compositions are useful for the production of molded and extruded articles.
