| Abstract: | The samples of CR-39 polymer (TASTRAK, Bristol, England) were annealled thermally at various temperatures ranging from 100°C
to 180°C for 1 hour, in air. FTIR spectroscopy reveals the structural degradation of CR-39 polymer due to thermal annealing
above its glass transition temperature. Optical band gap of pristine and thermally annealed samples has been determined using
UV-Visible absorption spectra. It has been observed that the optical band gap decreases continuously as a result of annealing.
