Abstract
A polyetherimide ester composition comprising the reaction products of: PA1 (i) a mixture of at least one high molecular weight diol and at least one low molecular weight diol; and PA1 (ii) a set of reactants selected from PA2 (a) (i) at least one high molecular weight poly(oxy alkylene)diamine, and (ii) at least one tricarboxylic acid or a derivative thereof, or PA2 (b) at least one high molecular weight polyoxyalkylene diimide diacid. Also a polyetherimide ester composition comprising the reaction products of: PA1 (i) at least one high molecular weight diol; and PA1 (ii) a set of reactants selected from PA2 (a) (i) at least one high molecular weight poly(oxy alkylene)diamine, and (ii) at least one tricarboxylic acid or a derivative thereof, or PA2 (b) at least one high molecular weight polyoxyalkylene diimide diacid.
