Abstract
Butyl acrylate was graft copolymerised onto cellulose extracted from pine needles by a simultaneous gamma radiation initiation method. Optimum conditions for the maximum graft yield are reported. Polymerisation and grafting parameters such as percentage grafting, percentage grafting efficiency, rate of polymerisation, homopolymerisation and graft copolymerisation were also determined. Grafted cellulose was further functionalised to produce poly(acryloyl hydroxylamine) [Cell-g-poly(CONHOH)] so as to generate active (-CONHOH)groups on the cellulose backbone. Graft copolymers were also characterised by elemental analysis by FTIR and by a swelling study. In addition, an attempt was made to study the sorption of ferrous ion and copper ions as model metal ions onto the candidate copolymers in order to investigate their selectivity in metal ion sorption and to determine the effect on metal ion sorption of the structural aspects of the hydrogels and other functionalised graft copolymers, so as to identify their end-uses. 11 refs.
