Novel high molecular weight diimide diacids and modified thermoplastic copolyether ester elastomers prepared therefrom

摘要

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.
