The graft copolymerization of methacrylonitrile onto kenaf fibers by a cerric ion-toluene redox pair was investigated in aqueous media. Graft yield of up to 212% was found, but the grafting efficiency was not greater than 17.6%. At varying concentrations of toluene, the conversion in graft yield pas

## Abstract The graft copolymerization of acrylic acid onto methylcellulose by ceric ion/__p__βxylene redox pair was investigated in aqueous media under homogeneous conditions. The graft yield dependency on __p__βxylene concentration in the range 1.8β45.0 Γ 10^β5^__M__ showed a minimum and an enhan
Polyacrylonitrile was grafted onto kenaf fibers in aqueous media by ceric ion-p-xylene redox system. The graft yield dependence on p-xylene concentration in the range 1.8 -45.0 Ο« 10 Οͺ4 M showed a minimum accompanied by an enhanced yield. This suggested the existence of two kinetically distinct graft
