Graft copolymerization of methylmethacrylate onto caesarweed fibers by the potassium permanganate–toluene redox system

摘要: Preliminary investigations have been conducted on the graft copolymerization of meth-ylmethacrylate onto Caesarweed fiber, initiated by potassium permanganate and toluene redox system. The percentage yield increased with up to 132% in concentration range, 1.0×10−2 5.0×10−2 M at 40°C. effects varying concentrations toluene, acids, monomer were also investigated. Graft initially then decreased from 2×10−2 20×10−2 M. temperature between 20 50°C. At 60°C, considerably 60% value calculated activation energies for overall reaction, initiation process, are 9.15 9.30 Kcal mol−1, respectively. © 1993 John Wiley & Sons, Inc.
