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.  ISSN : 0970-020X  Journal Name : Oriental Journal of Chemistry, Volume 24, Issue 1, January 2008, Pages 35-42  Volume : 24  Issue Number : 1  Publishing Year : 2008 AH 2008 AD  Number Of Pages : 8  Article Type : Article  Added Date : Thursday, October 15, 2009  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email اقبال محمد ابراهيم اسماعيل Iqbal Mohmmad Ibrahim Ismail Researcher Doctorate iismail@kau.edu.sa Alshehry, S.D Alshehry, S.D Researcher Doctorate   Back To Researches Page
