Abstract

In this paper, grafting reaction of acrylamide onto pre-irradiated polypropylene fibers in inert medium (N 2) has been studied. The grafting degree has been determined as a function of radiation dose, monomer concentration, temperature and reaction time. The experimental results showed that the best condition of grafting reaction was 10% methanol/water solvent, temperature 70℃, and reaction time 3 h. The mechanism of grafting reaction was characterized with ESR.
