Abstract
Graft copolymerization of acrylamide (AM) onto jute fibers has been studied in aqueous solution using a new class of acidic peroxosalt “potassium monopersulphate” as the initiator, under the catalytic influence of Fe(II) in a nitrogen atmosphere. It was observed that the graft yield was influenced by the reaction time, temperature, and concentration of the monomer, initiator, and base polymer. The grafting reaction has also been studied in the presence of a number of salts and organic solvents. The maximum graft yield (75.3%) was observed at 25°C at the concentrations of monomer (1.2 M), initiator (12.9×10−3 M), and catalyst (1.0×10−3 M) for a reaction time of 4 hours. From the experimental results a suitable mechanism for graft initiation and termination has been suggested. The graft copolymers have been characterized and their improved properties have been tested.
