Abstract
The small-angle X-ray scattering (SAXS) technique was used to investigate various macromolecular structural parameters of gamma-irradiated graft copolymers of methyl methacrylate (MMA) onto Nylon-6 fibres that were further subjected to different doses of gamma-rays to study the effects of radiation. It has been observed that SAXS profiles of various samples undergo drastic change with increase in dose and also they deviate from Porod’s Law, indicating that they can be classified under non-ideal two phase structure characterized by continuous variation of electron density at the phase boundary. The theories developed by Vonk and Ruland for non-ideal two phase structures have been applied to calculate various macromolecular parameters. The three and one-dimensional correlation functions have been computed from the background corrected SAXS profiles and various parameters like the width of the transition layer, the average periodicity transverse to the layer, the specific inner surface, the length of coherence, the transversal lengths in matter and in void, the range of inhomogeneity, the volume fractions of matter and void, the volume fraction of transition layer and characteristic number have been determined.
