General description

Aquivion® PFSA PW series grades are coarse powders based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF2=CF2-O-(CF2)2-SO2F industrially produced by Solvay Specialty Polymers. The resulting perfluoropolymer′s functional groups are in their sulfonic acid form, SO3H.

Application

  • Aquivion® PW79S acid powder exhibits concentrated ion cation-exchange capacity and can be used under the conditions where conventional exchange resins have shown insufficient chemical resistance.
  • Given the resin′s superacid functionality with many active groups it can also be used either directly or as an ingredient of composite structures active as heterogeneous catalysts. This encompasses a wide range of organic synthesis and respective reaction mechanisms, as already described in public literature.
