Ceric ammonium nitrate (CAN)-initiated graft copolymerization of methyl acrylate (MA) onto sodiumsalt of partially carboxymethylated tamarind kernel powder (Na-PCMTKP, DS = 0.15) was studied inan aqueous medium by solution polymerization technique. The growth of the graft reaction wasmonitored gravimetrically. The role of various synthesis variables on the grafting yields was examinedto achieve the maximum graft yields (%G = 278.27, %GE = 94.38, %Hp = 5.62) and the influence ofthe synthesis variables in the graft copolymerization has been discussed. The reactivity of methylacrylate (MA) towards graft copolymerization was compared with that of acrylonitrile (AN) on thebasis of the results obtained from the earlier studies and plausible explanation was furnished for theobserved reactivity of both the monomers towards grafting. The evaluated optimized reaction conditionswere utilized to study the effect of reaction medium on grafting and it was found that reaction mediumplays an important role in graft copolymerization. In order to ascertain the grafting, characterizationof the samples made by FTIR, TGA and SEM was conducted. The synthesized novel graft copolymermay find potential application to be used as metal adsorbents.
