Direct and preirradiation graft of styrene on cotton cellulose were st
udied in respects of molecular weight ((M) over bar n), molecular weig
ht distribution ((M) over bar w/(M) over bar n) of grafted side chains
and reaction kinetics. Effects of total dose, dose rate, concentratio
n of monomer and acidity in the systems on (M) over bar n and (M) over
bar w/(M) over bar n of the grafted side chains were investigated by
means of direct radiation grafting. Preirradiation grafting of the sam
e systems was studied as well.
