规格用途
| 备注说明 | Aquivion® PW87S is a coarse, acid powder based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF2=CF-O-(CF2)2-SO2F produced by Solvay. The resulting perfluoropolymer's functional groups are in their sulfonic acid form, SO3H. Aquivion® PW87S is chemically-stabilized (denoted by the S-suffix).Aquivion® PW87S exhibits ionic exchange capacity and it can be used as is under conditions where conventional exchange resins have shown insufficient chemical resistance.Due to its superacid functionality with many active groups, it can be used either directly or as an ingredient of composite structures active as a heterogeneous catalyst. This encompasses a wide range of organic syntheses and respective reaction mechanisms.PW87S is a good trade-off between polymer crystallinity and ionic exchange capacity. It is insoluble in water, acid or bases and in most solvents unless extreme conditions would be applied.Furthermore, Aquivion® PW87S can be dissolved in some organic solvents to produce ion exchage capacity membrane. Proper organic solvents are dipolar aprotic such as N-ethyl-2-pyrrolidone (NEP) and dimethyl sulfoxide. To facilitate the dissolution slightly increase the temperature to 50-60°C.Please visit Aquivion.com for more information. |
