Nylon 6 has been graft copolymerized with acrylamide using a quinquevalent vanadium ion as an initiator in aqueous media under a variety of conditions. Effects of initiator concentration, monomer concentration, acid concentration, CuSO 4 concentration, temperature, and chain transfer solvents have been studied. The graft yield shows a maxima at 0.005 mole/liter of initiator concentration. Similarly, the graft yield maxima with respect to acid concentration is 0.45 mole/liter. The graft yield increases within the range of the monomer concentration studied. The graft yield is temperature dependent. In addition, the reactions involved in initiation of grafting are elucidated. The work was also extended to study the moisture regain of grafted samples.
