Novel high molecular weight diimide diacids and modified thermoplastic copolyether ester elastomers prepared therefrom
First Claim
1. The imidization reaction product of(a) a tricarboxylic acid anhydride or the corresponding acid thereof containing two vicinal carboxyl groups and(b) a polyoxyalkylene diamine of the formula
wherein G is the divalent radical remaining after the removal of the amino groups of a long chain poly(alkylene ether) diamine having a molecular weight of from about 600 to about 12000 and a carbon to oxygen, ratio of from about 1.8;
1 to about 4.3;

Abstract
Novel diimide diacids and modified polyetherimide esters are prepared therefrom by reacting diols, dicarboxylic acids and a combination of the novel diimide diacid and dimer acid. These compositions have many excellent properties which make them particularly useful for extrusion and molding applications.
