EFFECT OF GAMMA RAYS IN THE PREPARATION OF POLYMER AND HYDROGEL FROM ACRYLAMIDE MONOMER

Received Date: 27 August 2002
Revised Date: 30 October 2002

The formation of polymer and hydrogel from aqueous solutions having 20, 30 and 40% concentrations ofacrylamide monomer by γ-ray irradiation processing in the dose range 0.06-30 kGy using a Co-60 source and theircharacterization have been observed. Polymer conversion and gel fraction are found to depend on radiation doses. Polymerconversion increases with the increase of dose, depending on the solution concentration, where maximum conversion isachieved at 0.18, 0.16 and 0.10 kGy for 20%, 30% and 40% concentrations,respectively.On the other hand,gel fraction increases with dose from the gel point(0.12 kGy) for all concentrations,where 100% conversion of gel occurs at doses ≥ 5 kGy.Tensile strength,wiscosity and molecular weight(Mw) of polymer samples increase with both the dose and the concentration,showing a high value of Mw up to ≈102.Swelling of hydrogels under water with respect to time varies due to the variation of cross-linking density formed in the gels and the maximum swelling mainly within 24 h.A remarkable change of surface morphology reveals characteristic features of monomer,polymer and hydrogel films.
