一般描述
Aquivion® P87S-SO2F are pellets 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 sulfonyl fluoride form, SO2F.
应用
- Aquivion® P87 pellets can be melt-pressed or extruded into plates, sheets or thin films down to about 50μm. The extruder shall be equipped with a standard three-zone metering screw devoid of barrier or mixing elements. Optimum temperature settings will depend on the configuration of the equipment but generally cover 100 to 300°C range. Optionally functional groups in the molded part are then hydrolyzed in baths or wet benches with a heated base (NaOH, KOH etc), reaction which may take minutes or hours, depending on thickness and conditions.
- Aquivion® P87 pellets can be directly hydrolyzed as described - either completely or only on their outer surface. This will enable functional activity of the sulfonic acid / sulfonyl salt groups for ion-exchange operations or as acid catalyst.
