Abstract
Graft copolymerization of o-toluidine (OT) onto Rayon fibre by using peroxy disulphate (PDS) and peroxomonosulphate (PMS) as an initiator in aqueous acidic medium under nitrogen atmosphere was carried out. Rate of homopolymerization, rate of grafting, % grafting and % efficiency were determined. Both rate of homopolymerization and rate of grafting showed first order dependence on [M], [I] and (amount of Rayon fibre). From the experimental results rate constants were evaluated. The modification of Rayon fibre in the form of chemical grafting was confirmed through FTIR, UV-Visible spectroscopy. Cyclic voltammetry, weight loss study and conductivity measurements. Probable mechanism has been proposed to explain the obtained experimental results.
