Redox initiated graft copolymerization of 4-vinyl pyridine onto wool fiber

摘要

The graft copolymerization of 4-Vinyl Pyridine(4VP)onto wool fiber in aqueous medium by peroxomonosulphate(PMS)-thioglycolic acid(TGA)redox pair in an inert atmosphere has been investigated.The effect of concentrations of 4VP,PMS,TGA on R_h,and graft parameters have been studied.In addition,the effect of time,temperature,and amount of wool fiber on R_h and graft parameters were also determined.Chemical grafting of 4VP onto wool fiber was confirmed by FTIR spectroscopy.The tensile strength of the grafts have been analyzed.
