Abstract

Binary vinyl monomers were grafted onto mulberry silk fibre in aqueous medium by using ceric ammonium nitrate (CAN) as redox initiator. Grafting of binary monomer mixtures of methyl methacrylate (MMA) with butyl acrylate (BA), ethyl acrylate (EA) acrylamide (AAm) and vinyl acetate (VAc) were reported earlier. FTIR, TGA and SEM techniques were used to characterize the graft copolymers. Swelling studies of grafted and ungrafted fibres was done with DMF, water, methanol and n-butanol. Graft copolymers were investigated for dye uptake (gentian violet) photo-calorimetrically at 420 nm.
