Graft copolymerization of acrylic acid to cassava starch-Evaluation of the influences of process parameters by an experimental design method

► Graft copolymerization of acrylic acid onto cassava starch with Fenton's initiator. ► Variables of relevance to copolymer synthesis were screened by experimental design. ► Temperature, starch concentration and its ratio to monomer are significant variables. ► Monomer conversion is always near 100% at all conditions.
