Abstract

Graft copolymerization of acrylonitrile (AN) onto potato starch (PS) using eerie ammonium nitrate as initiator was
accomplished. Before grafting starch was gelatinized in two ways; one is dispersing PS in water and other in aqueous
butanol. The results show that PS gelatinized in aqueous iso-butanol facilitates the grafting of growing polymer chain of AN
onto backbone slightly better than PS gelatinized in water. The effects of monomer, backbone and catalyst concentration on
rate of conversion of monomer, rate of graft copolymerization, rate of homopolymerization, grafting efficiency and grafting
rate are discussed in detail. The absorbency of saponified products of each sample was determined in distilled water, tap
water and aqueous solution ofNa Cl and KCl and discussed thoroughly.
