Description
Summary:High molecular weight polyspiroimides have been prepared by reacting diamines with the dianhydride of carboxymethanetetraacetic acid in polar organic solvents. Alternatively, thermal condensation of the preformed salt made from equimolar amounts of diamine and methanetetraacetic acid (MTA) can be used. These all‐aliphatic polyimides are soluble in certain organic solvents, and possess good thermal‐oxidative stability.
