Polymethyl methacrylate, PMMA, is one of the most important thermoplastic material which can be used as replacement of glass due to its unmatched properties. But PMMA is prone to UV and thermal degradation. So to overcome this drawback, along with PMMA, UV absorber is incorporated which not only acts as a stabiliser but also inhibits 60% of degradation. It also provides better thermal stability at 70°C. Thus incorporation of UVA prolongs the life span and activity of PMMA. Thus enabling it to be used in commercial preparation. The additive efficiency was confirmed using UV-Vis and FT-IR studies.
