Abstract
Treatment of Poly(chlorotrifluoroethylene) (in the forms of Kel-F 6061 and Neoflon M400H) with Zn/SO2 in DMF results in substitution of the chloride ligand with the sulfinic acid moiety. Subsequent oxidation af fords the sulfonic acid. The materials are characterized by elemental analysis, titration, scanning electron microscopy, and FT-IR. ATR-IR s tudies indicate that functionalization is probably Mot a surface-selec tive phenomenon. (C) 1998 John Wiley & Sons, Inc.
