Procedure

The diazonium salt of 4-aminostyrene is prepared as described above from 3.6 g aminostyrene, 2.1 g sodium nitrite, and 150 g water. Ethanol, 10 g, is added to completely dissolve the diazonium salt. A solution of SA-treated MMC is added to the diazonium salt solution, and it is allowed to react for 18 hours under mixing. The solution is filtered to provide MMC solution at about 11 wt %. This MMC contains both benzenesulfonic acid and styrene functionalities covalently attached to the MMC particle.
