GAMMA-PREIRRADIATION AND GRAFTING OF 2N-MORPHOLINO ETHYL-METHACRYLATEONTO POLYPROPYLENE FABRIC

The radiation-induced grafting of BN-morpholino ethyl methacrylate (ME MA) in aqueous solution onto polypropylene fabric by a preirradiation technique has been investigated. Among the most important factors affe cting the graft yield are monomer concentration, irradiation dose, rea ction temperature, and time. It was found that the graft yield increas ed with increasing monomer concentration, grafting temperature, and pr eirradiation dose. The kinetic studies showed that the dependence of t he grafting rate on monomer concentration is of 1.1 order. Moreover, t he calculated overall activation energy was 14.2 kcal/mol. The grafted PP fabric shows an increase in moisture regain with increasing graft yield. Also, the dyeability with acid dye was significantly increased due to grafting with MEMA.
