AN INVESTIGATION OF THE GRAFTING OF CELLULOSE POWDER WITH ACRYLAMIDE UNDER A MAGNETIC-FIELD

Cellulose powder obtained from oak furfural lignocellulose by nitratio n reaction was grafted with acrylamide using a radical initiation. The grafting reactions were carried out and compared both in presence and in absence of a continuous external magnetic field with the intensity extended between 0.15-0.35 T. The effect of monomer and initiator con centration, time and temperature of reaction and magnetic field intens ity onto the grafting process were examined. It was observed that the presence of a magnetic field leads to a significant increase of the gr aft conversion.
