| Abstract: | The use of trivalent manganese to initiate graft-copolymerization of acrylamide onto nylon-6 has been investigated. The rate of grafting has been determined by varying monomer, manganese(III), temperature and solvent mixtures. The graft yield increases with increasing monomer concentration up to 0.8 M and with further increase of monomer concentration the graft yield decreases. The percentage of grafting increases with managanese (III) ion concentration up to 5.25 × 10?3 M and thereafter it decreases. The rate of reaction depends on temperature. Among the solvent composition studied, a water/solvent mixture containing 25% of the solvent seems to constitute the most favourable medium for grafting and with further increase of solvent composition, the graft yield decreases. |
