✦ Synopsis

Graft copolymerization of poly(aniline) and poly(o-toluidine) onto poly(ethylene terephthalate) fiber was conducted by using peroxydisulfate as a lone initiator under nitrogen atmosphere at various experimental conditions in aqueous hydrochloric acid medium. The grafting of poly(aniline) and poly(o-toluidine) onto poly(ethylene terephthalate) fiber was verified by recording cyclic voltammetry of the grafted fiber, conductivity measurements, and thermal analysis. Graft parameters-such as % grafting, % efficiency, and the rate of grafting-were followed. Grafting was always accompanied by homopolymerization. The rate of homopolymerization was also followed in all experimental conditions.

The grafting of acrylamide onto poly(ethy1ene terephthaiate) fibers using hydrogen peroxide as the redox initiator was investigated. Benzyl alcohol was found to be the favorite medium for this grafting. Maximum graft yield (7.6%) was reached at 95°C; the graft yield decreased at higher temperatures,
