Photograft Copolymerization of Methyl Methacrylate (MMA) on Bleached Jute Fiber Using Ferric Sulfate, Fe2(So4)3, as Initiator in Limited Aqueous System

Abstract

The polymerization of methyl methacrylate in the presence of bleached jute with Fe₂(SO₄)₃ as initiator under visible light was studied. In order to establish the optimum reaction conditions for graft copolymerization of MMA on bleached jute, the variables studied were copper number of bleached jute to give a measure of the degree of oxidation effected by bleaching (hypoclorite treatment), initiator concentration, monomer concentration, amount of bleached jute, and time of polymerization. The reaction mechanisms for graft copolymer and homopolymer formation are discussed. Percent total conversion, % grafting, and grafting efficiency (%) under different conditions are evaluated and compared. High grafting efficiency (∼80%) along with high conversion (N80% in 2–3 h) and high % grafting were readily obtained.
