A study on grafting of methyl methacrylate onto jute fiber (S2O 82−‐thiourea redox system)

摘要

AbstractA study of the graft copolymerization of methyl methacrylate onto jute fiber, using K2S2O8‐thiourea (TU) redox‐initiating system has been made. The effects of concentration of monomer, S2O 82−, TU on graft yield have been studied. Besides the effects of time, temperature, acid, and amount of jute fiber, some inorganic salts and organic solvents on graft yield have been investigated. The most remarkable features of the investigation include proposition of a mechanism for the grafting process and characterization of grafted fiber by infrared (IR) and thermogravimetric studies. Grafting has improved the light fastness of jute fibers dyed with basic dyes. More than 200 graft yield could be achieved in the present invest
