牌号简介	Aquivion® PW98是一种粗糙的酸性粉末，基于由Solvay生产的四氟乙烯和磺酰氟化物乙烯基醚（SFVE）CF2=CF-O-（CF2）2-SO2F的短侧链（SSC）共聚物。所得到的全氟聚合物官能团呈磺酸形式，SO3H。Aquivion® PW98具有离子交换能力，在常规交换树脂显示出不充分的耐化学性的情况下，可以按原样使用。考虑到树脂具有许多活性基团的超强酸功能性，它也可以直接或作为复合结构的一种成分，作为多相催化剂。这包括广泛的有机合成和各自的反应机制。PW98的特点是聚合物结晶度高。它不溶于水、酸或碱以及大多数溶剂，除非使用极端条件。此外，Aquivion® PW98还可以在一些有机溶剂中溶解，产生离子交换膜。合适的有机溶剂为偶极非质子，如N-乙基-2-吡咯烷酮（NEP）和二甲基亚砜。为了便于溶解，请将温度稍微升高到50-60°C。有关更多信息，请访问aquivion.com。 Aquivion® PW98 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® PW98 exhibits ionic exchange capacity and it can be used as is under 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 syntheses and respective reaction mechanisms. PW98 is characterized by a high degree of polymer crystallinity. It is insoluble in water, acid or bases and in most solvents unless extreme conditions are applied. Furthermore, Aquivion® PW98 can be dissolved in some organic solvents to produce ion exchage capacity membranes. 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.

Aquivion® PW79S基于四氟乙烯与磺酰氟化物乙烯基醚（sfve）cf2=cf-o-（cf2）2-so2f的短侧链共聚物的粗酸性粉末。生成的全氟聚合物的官能团是以磺酸形式存在的，SO3H。Aquivion® PW79S是化学稳定的（用S后缀表示）。Aquivion® PW79S的特点是等效重量低，离子交换能力强。在常规交换树脂耐化学性不足的情况下，也可以使用。由于它具有许多活性基团的超强酸功能，因此可以直接使用，也可以作为复合结构的一种成分，作为一种多相催化剂。这包括广泛的有机合成和各自的反应机制。它不溶于水、酸或碱以及大多数溶剂，除非使用极端条件。此外，Aquivion® PW79S还可以在某些有机溶剂中溶解，产生离子交换膜。合适的有机溶剂为偶极非质子，如N-乙基-2-吡咯烷酮（NEP）和二甲基亚砜。为了便于溶解，请将温度稍微升高到50-60°C。有关更多信息，请访问aquivion.com。 Aquivion® PW79S 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® PW79S is chemically-stabilized (denoted by the S-suffix).
