摘要：

The effect of a bifunctional monomer, divinyl benzene (DVB) on the graft copolymerization of styrene onto cotton cellulose was studied using uranyl nitrate (UN) and benzoin ethyl ether (BEE) as photoinitiators. UN gave higher graft add-on as compared to BEE. Incorporation of DVB in the grafting bath containing styrene led to a great enhancement of graft add-on which was higher than that obtained by using cotton preswollen with sodium hydroxide as substrate. With increase in the graft add-on, the moisture regain and tenacity decreased, whereas thermal stability of cotton improved.
