Abstract
Structure and optical property studies using IR & UV spectroscopy, refractive index measurement and X-ray diffraction were performed on poly (vinyl chloride), PVC, stabilized by para-ethyl carboxy N-phenyl maleimide (PEC-NPMI) additive. The effect of addition of the stabilizer PEC-NPMI, with different concentrations, was studied. The results indicate that the addition of PEC-NPMI with 0.01 r g/1 r g PVC enhances the isotropic nature of the PVC polymer. Furthermore the effect of laser radiation on the optical properties of the 0.01 r g PEC-NPMI/1 r g PVC polymer was studied. The study shows that the PVC stabilized with 0.01 r g PEC-NPMI/1 r g PVC and irradiated with 4.27 r J/cm 2 infrared laser radiation is most suitable for applications requiring PVC of high absorbance value in the IR and UV regions.
