Graft copolymerization of AN onto cassava starch gelatinized by alkali at room temperature has been studied using KMnO₄ as initiator in acid solution. Result showed high monomer convertion to polymer (80%), very high graft efficiency (95%), and high molecular weight of graft polymer (3×10⁵). The hyorolyzate of graft copolymer can absorb up to over 2000 times of water (g/g).
