Summary: | An acrylate ester polymer composition having the desirable optical properties of poly(meth)acrylates and an enhanced Tg comprises a blend of a conventional PMMA polymer or copolymer with a high Tg acrylate ester polymer prepared by pyrolyzing a copolymer of methyl methacrylate and t-butyl methacrylate. The blend exhibits a single Tg, intermediate between the Tg of the conventional PMMA polymer and that of the pyrolyzed methyl methacrylate/t-butyl methacrylate copolymer. The blend can be formed into products that have good clarity, low haze and low color. |
