Effect temperature on the isolators properties electerical to sampeles unsaturated polyster.

Abstract

The effects of annealing at temperatures (80Ċ,50Ċ,30Ċ) on the pure unsaturated polyester . Have been studied though the electric properties: impedance, dielectric constant, loss factor and a|.c . conductivity .the effects of annealing caused decreasing in impedance and increasing in dielectric constant loss factor as well as in a c conductivity these changes can be attributed due to the crosslinking to the molecular structure of the polymer.
