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.

High heat distortion temperature methacrylate polymer blends

A curable coating composition for preparing an anti-static coating contains from about 50% by weight to about 90% by weight of a dispersion of colloidal silica and a curable methylsilsesquioxane in a lower (C.sub.1 -C.sub.5) alkanol, and from about 10% by weight to about 50% by weight of an aminofunctional silane component.

Polysiloxane abrasion and static resistant coating

A curable coating composition for preparing an anti-static coating contains at least one addition polymerizable ethylenically unsaturated monomer, a perfluoro ionic surfactant, and a polyethoxy or fluorinated polyethoxy auxiliary compound. The perfluoro ionic surfactant and the polyethoxy or fluorinated polyethoxy auxiliary compound are present in the composition in amounts effective to impart static-dissipative properties to polymerized coatings prepared therefrom.
