Abstract
A crosslinked polyetherimide ester polymer comprised of the reaction products of: PA1 (i) at least one diol; PA1 (ii) at least one dicarboxylic acid or an ester forming derivative thereof; PA1 (iii) a set of reactants selected from PA2 (a) (1) at least one high molecular weight poly(oxy alkylene)diamine, and (2) at least one tricarboxylic acid or its derivative, or PA2 (b) at least one high molecular weight polyoxylene diimide diacid; and PA1 (iv) a crosslinking effective amount of at least one crosslinking agent.
