“…G.B. Pariiskii et al [11] studied the effect of chlorine on PMMA and concludes chlorine can react with the terminal double bond, carbonyl group, and the methyl group, but in the present study, chlorine reacts with the carbonyl or conjugated bond and not over the other region of PMMA.

Aim: The aim of this study was to evaluate the effect of concentration of chlorine on the polymethylmethacrylate and the influence of chemical properties of polymethylmethacrylate using ultraviolet-visible spectroscopy.Materials and methods: A total 30 acrylic blocks of dimensions 65X 13X 3 mm as per specification of ASTM [American standard for testing materials] were made in heat cure denture base resin to evaluate the effect of chlorine on polymethylmethacrylate. 30 samples were divided into 3 groups of 10 samples in each. Group I was stored in artificial saliva which acts as a control group, Group II was stored in 3ppm concentration of chlorine and Group III was stored in 100ppm concentration of chlorine.Results: Ultraviolet rays are passed into the sample, the results are obtained on a graph with wavelength in nanometer on X axis and the percentage of reflectance on Y axis. If an organic compound absorbs ultraviolet radiation, it means that the compound contains carbonyl or conjugated double bonds3. Since polymethylmethacrylate absorb ultraviolet rays, the existence on this bonds are confirmed in graph.Conclusion: Within the limitations of the study it was concluded that the effect of chlorine on polymethylmethacrylate can react over the conjugated bond or carbonyl group at higher concentration, whereas the action of chlorine is negligible at lower concentration.
