Graft copolymerization of acrylonitrile onto jute fibers (studies on Ce(IV)‐hippuric acid redox system)

Graft copolymerization of acrylonitrile (AN) onto chemically modified bleached jute fibers was studied using Ce(IV)‐hippuric acid redox initiator system. The effects of time, temperature, concentration of monomer (AN), metal ion (Ce4+), hippuric acid, sulfuric acid, and amount of jute fiber on graft yield have been studied. The effects of some organic solvents and inorganic salts on graft yield have also been studied. Infrared spectra of chemically modified bleached jute and grafted jute have been taken and their characteristic bands have been identified. More than 90% graft yield could be achieved with the present system.
