Abstract: Mass spectra of reconstructed ion chromatogram (MRIC) technique are used to follow up the grafting copolymerization of 1-vinyl-2-pyrrolidinone (VP), 1-vinyl-3-anisylidine-2-pyrrolidinone (VAP) and ethylmethacrylate (EMA) and cellulose extracted from kenaf using xanthate method. Grafting is carried out under ionic and/or free radical mechanism conditions. Factors affecting grafting yield such as temperature, sodium hydroxide concentration, liquor ratio, carbon disulfide concentration, monomer and grafting time have been studied. Keywords: Cellulose, Cellulose xanthate, Ethylmethacrylate, 1-vinyl-2-pyrrolidinone, 1-vinyl-3-anisylidine-2-pyrrolidinone.Download Full Article |
