Abstract
Aliphatic alcohol, and high boiling point hydroxy compound additives are added to poly methyl methacrylate to improve the ultraviolet radiation resistance of the polymer. The additives may be incorporated into the poly methyl methacrylate by including the additives with the monomers prior to polymerization. Alternatively, the additives may be incorporated into the poly methylmethacrylate by addition to polymerized methyl methacrylate.
