| Abstract: | The use of tetravalent cerium to initiate graft copolymerization of methyl methacrylate on to silk fibres has been investigated. The extent of grafting was determined while varying Ce(IV) and monomer concentrations, temperature and nature of the fibre. The graft yield increased on increasing Ce(IV) concentration up to 0.015 M and monomer concentration up to 0.469 M; thereafter it decreased. The effect of an inorganic salt (copper sulphate) on grafting has also been studied. Chemical modification of the silk prior to grafting noticeably affected graft yield. |
