Abstract
The graft copolymerization of glycidyl methacrylate (GMA) on jute fibers at ambient conditions is the desired goal. Graft copolymerization of (GMA) on jute fibers was carried out using Ammonium Persulphate Acetone Sodium Bisulphite (APS/ASBS) initiating redox system. The grafting reaction was studied with respect to graft yield (GY), grafting efficiency (GE) and total conversion (TC). Factors such as pH value, liquor ratio (L: R), redox initiator concentration, addition sequence, reaction time, temperature and GMA concentration [M], were investigated. The results obtained showed that the optimal grafting yield is obtained at the following conditions: initiator concentration of 20/40 mmole/l for APS/ASBS respectively, liquor ratio(I:20), pH value 3, time 120 min., temperature 20°C, and monomer concentration [M] 150% based on weight of substrate (OWS). Grafted and scoured jute fibers were characterized via thermal gravimetric analysis (TGA) and infra red spectroscopic analysis (IR).
