heal.abstract	Three simultaneous crosslinking and sulfonation reactions were developed, in order to obtain hydrophilic gels from recycled hydrophobic commercial materials. In the first case we employed pulverized fountain pens (Bic) in the absence of solvent. Shaving products (Gillette Blue) and fountain pens (Bic) as well were dissolved in chlorinated solvents and further modified with agents bearing chloromethyl groups in the second and third case respectively. In many cases, the products of these reactions showed high ion-exchange capacities and high swelling degree in water. The swelling behaviour of these resins in solutions of low ionic strength was used so as to increase their ability to swell in water permanently. A swelling ratio of almost 200 was obtained for slightly crosslinked hydrogels according to that treatment at room temperature. The final products may have all the applications of sulfonated polystyrene resins.	en
