Poly(diallyldimethylpyrrolidinium) bis(trifluoromethylsulfonyl)imide, >98%, CAS: 521942-10-9

Poly(diallyldimethylpyrrolidinium) bis(trifluoromethylsulfonyl)imide (Poly(DiMPyrr) TFSI, also known as PDADMA TFSI, CAS 521942-10-9) is a polymeric ionic liquid. It pairs a polycationic pyrrolidinium backbone with the TFSI⁻ anion. Because TFSI is a hydrophobic anion, the polymer is generally less sensitive to moisture than conventional polyelectrolytes such as PDADMA chloride. As a result, it is suited to electrolytes, coatings and membranes where water uptake is a concern.
