Abstract

Grafting of acrylonitrile (AN) onto rice starch was accomplished using eerie ammonium nitrate (CAN) as catalyst. The
effect of monomer, backbone, catalyst concentration on rate of conversion of monomer (Rp), rate of graft copolymcriza-
tion (Rg), grafting effeciency (GE), grafting ratio (GR) is discussed. The absorption of water obtained from different
sources by saponified product or gran copolymer was determined. The increment in absorbancy (g I-Ip g.l) is due to the
formation or carboxyl anions (-COOo) in the polymer network which develops strong electrostatic forces. The effect of
aqueous sodium chloride on saponified product is also discussed.
