Photo Stabilizing Efficiency Of Poly(methyl methacrylate) Based On Metal
Ion Complexes Of Saccharine
The photostabilization of poly(methyl methacrylate) (PMMA) films having saccharine complexes of Zn(II), Cd(II), Hg(II), Fe(III), Ni(II) and Cu(II) complexes
was investigated. The production of PMMA films containing such complexes
(0.5% by weight) was carried out by the casting method using THF. The photostabilization activities of the compounds were determined by monitoring the carbonyl and hydroxyl index with irradiation time. Evaluation of stabilizing efficiency of PMMA by ultra-violet spectroscopy to investigate photodecomposition
rate constant (kd) for PMMA films in the absence and presence of saccharine
complexes. The changes in the viscosity average molecular weight of PMMA with
irradiation time were evaluated. The rate of photostabilization for PMMA in the
presence of the additives was found to follow the order Ni(sac) > Cu(sac) >
Zn(sac) > Cd(sac) > Hg(sac) > Fe(sac). Depending on the structure of the additive,
such as a peroxide decomposer, UV absorption or a radical scavenger for the
photostabilizer.
Keywords: Photodegradation, UV stabilizers, PMMA, Saccharine.
