Abstract
A study on modification of dielectric properties of polyacetate polymer is studied in the dose range of 101 –106 Gy. It is observed that significant increase in dielectric constant takes place at the higher doses of gamma radiation. This increase is observed mainly in the lower frequency region especially in the range of 42 to 1000 Hz. The increase in dielectric constant is attributed to polarization in the polymer matrix caused due to chain scissioning and subsequent rearrangement of the polymeric chain in the matrix
