optical study on polymethyl methacrylate polyvinyl acetate

Polymers Flashcards Quizlet

Polymethyl Methacrylate. More commonly known as perspex PMMA is formed by the free radical addition polymerization of methyl methacrylate in the presence of an organic peroxide at about 60C. PMMA is a dense, transparent and tough solid makes it a good material for making safety goggles, advertising sign boards and vehicle light protectors
