| titleOfInvention | 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 with phosphite group. The methacrylate series polymer includes methacrylate series monomer unit and acrylate series monomer unit, and has weight average molecular weight (Mw) of 20,000 to 200,000. The styrene series-maleic anhydride series copolymer includes from 65 wt% to 85 wt% of styrene series monomer unit, from 15 wt% to 35 wt% of maleic anhydride series monomer unit, and from 0 to 20 wt% of second copolymerizable monomer unit. The content range of the aromatic compound with phosphite group is from 200 ppm to 900 ppm based on 100 parts by weight of the methacrylate series polymer and the styrene series-maleic anhydride series copolymer. |
