Graft polymerization of GMA onto polymer substrates is advantageous because the epoxy group of GMA is modified easily to give functions such as ion exchange and adsorption of toxic gases, with the original properties remaining intact. Glycidyl methacrylate(GMA) was grafted onto Kapok fiber(plant fiber) by irradiation method using a 60Co gamma ray. The Kapok fiber used in this work was treated with NaClO2 to remove phenolic compounds especially, lignin or with NaIO4 to introduce aldehyde groups from glycol groups of polysaccharides. Gamma ray irradiation from a 60Co was used to carry out GMA grafting onto Kapok fiber. The absorbed dose and dose rate ranged from 1-4 kGy and 1 kGy/h, respectively. The effects of the absorbed dose and monomer concentration on the degree of grafting were investigated. The physical and chemical properties of the GMA grafted Kapok fiber was investigated. |
