Synthesis of polyacrylamide (PAM) grafted soya peptone was performed by the microwave assisted method using ceric ammonium nitrate (CAN) as free radical initiator. The synthesis was optimized by varying the acrylamide and CAN concentration. The grafting of the PAM chains on the peptone backbone was confirmed through various physicochemical techniques-intrinsic viscosity study, FTIR spectroscopy, elemental analysis (C, H, N, S and O), SEM and TGA. The applicability of this synthesized graft copolymer as a water soluble adhesive has been studied by fabricating a single lap joint of two wooden blocks using an aqueous paste of the graft copolymer as adhesive. After curing, the breaking point of the joint was determined using an UTM.
