Polymethacrylate composition and optical device made therefrom, and display apparatus |
| abstract |
A polymethacrylate composition, an optical device made therefrom, and a display apparatus are provided. The polymethacrylate composition includes 50 to 85 parts by weight of methacrylate series polymer, 15 to 50 parts by weight of styrene series-maleic anhydride series copolymer, and an aromatic compound having a phosphite group. The methacrylate series polymer includes methacrylate series monomer unit and acrylate series monomer unit and has a weight average molecular weight (Mw) in a range between 20,000 and 200,000. The styrene series-maleic anhydride series copolymer includes 65 wt %-85 wt % of styrene series monomer unit, 15 wt %-35 wt % of maleic anhydride series monomer unit, and 0-20 wt % of second copolymerizable monomer unit. The content of the aromatic compound having a phosphite group in the polymethacrylate composition is 200 ppm-900 ppm. |
