GRAFT COPOLYMERIZATION OF ACRYLONITRILE ONTO CASSAVA STARCH INITIATED BY KMnO4 AND HYDROLYSIS OF GRAFT COPOLYMER
Abstract:
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).
