Poly(diallyldimethylpyrrolidinium) bis(fluorosulfonyl)imide, >98%

Poly(diallyldimethylpyrrolidinium) bis(fluorosulfonyl)imide (Poly(DiMPyrr) FSI, also known as PDADMA FSI) is a polymeric ionic liquid. It pairs a polycationic pyrrolidinium backbone with the mobile FSI⁻ anion. As a result, it combines the ion transport of an ionic liquid with the film-forming and mechanical properties of a polymer. Because it is non-volatile, it is suited to solid-state and high-temperature applications where liquid electrolytes are not practical.

Key Applications
