Grafting of 4-aminoantipyrine from guar gum substrates using graft atom transfer radical polymerization (ATRP) process

► Guar gum as an ATRP initiator has been synthesised for living radical graft copolymerization of AAP. ► This methodology gives graft copolymer without formation of homopolymer. ► Good conversion rate gives more potential and functional material based on guar gum. ► The initial mole ratio of the reactants [AAP]:[GGBr]:[Cu(I)Br]:[bpy] was found 100:1:1:2.
