N2 - Commercial polyetheretherketone (Victrex PEEK) was sulfonated up to 90% degree of sulfonation (DS), then reacted with SiCl4 to obtain
a hybrid polymer. The product was characterized by 29Si NMR and ATR/FTIR spectroscopies demonstrating the formation of covalent bonds
between the organic and inorganic components. No dispersed inorganic silicon was present in the product as evidenced by the lack of any
resonance at δ<-100 ppm. Despite the high DS the physicochemical properties of the hybrid were suitable for the preparation of
membranes exhibiting high and stable conductivity values (10-2 S/cm), hence suitable for application as ion exchange membrane. © 2004 Elsevier Ltd. All rights reserved.
