Sulphonated polyetherimide

Rajagopalan etal. [4] reported the synthesis of sulphonated polyetherimide and subsequent synthesis of ionic polymer metal composites (IPMC) by depositing platinum on both sides of the polymer membrane by electroless plating process for use in actuators. The TGA and NMR analysis confirmed the successful incorporation of sulfonic groups in the polymer backbone. The content of sulfur in the polymer membrane was measured to be 4.68% by EDX analysis and the degree of sulfonation could also be controlled. SEM micrographs of the composite membrane also confirmed the uniform formation of small platinum particles on the surface of polymer membrane as shown in Figure 1.5. The thickness of...

In addition to LARC-TPI, further recent developments have included the polyimide sulphones, polysiliconeimides and polyetherimides. All three have been evaluated and have shown promise for adhesive bonding apphcations. 

With very densely crosslinked polymers, rubbers are ineffective as toughening agents. Thermoplastic additives are used instead, such as polyethersulphones, polyamides and polyetherimides. Like the butadiene-acrylonitrile copolymers mentioned above, the sulphone additives can be fimctionalised with hydroxyl or amine end-groups.
