<p>THERMOPLASTIC POLYETHERIMIDE ESTER ELASTOMERS Novel polyetherimide esters are prepared from diols, dicarboxylic acids and polyoxyalkylene diimide diacids and novel modified polyetherimide esters are prepared from diols, dicarboxylic acids and a combination of polyoxyalkylene diimide diacids and dimer acid. These compositions have many excellent properties which make them particularly useful for extrusion and molding applications.</p> |
