| Abstract: | Aging of polystyrene and styrene-acrylate copolymers had been quantitatively investigatedwith UV-Vis and FITR spectroscopy.Under the action of light,heat and oxygen,somemain chains and side benzene groups of these polymers were broken off. A littleacetophenone structures appeared,and made the materials coloured. |
