Transparent films based on resin components having a high glass transition temperature

A film comprising a resin component having a Tg of at least about 115° C. and a weight average molecular weight of at least about 90,000 g/mole but not more than 250,000 g/mole, the resin component comprising:

• a) at least one copolymer of methyl methacrylate, methacrylic acid and, optionally, at least one additional co-monomer, wherein the at least one copolymer comprises about 94 to about 98.5% by weight methyl methacrylate and has a weight average molecular weight of 70,000 to 80,000 g/mole, and
• b) at least one additional polymer selected from the group consisting of a copolymer of methyl methacrylate and methyl acrylate or ethyl acrylate, and, optionally, at least one additional co-monomer selected from a vinyl aromatic monomer, cyclic and aliphatic unsaturated anhydrides and cyclohexyl methacrylate, wherein the at least one additional polymer has a weight average molecular weight of at least 120,000 g/mole and wherein the copolymer comprises 80 to 99% by weight methyl methacrylate,
• wherein the film has a light transmission of at least about 90% and less than about 1% haze, and
• wherein the resin component additionally comprises at least one antioxidant selected from the group consisting of phosphite antioxidants, phosphate antioxidants, phosphonate antioxidants, phosphine antioxidants, phenolic antioxidants, triazinetrione antioxidants and combinations thereof.
