Abstract: A method for producing a thermoplastic sheet includes extruding a composition including a melt polycarbonate resin having a Fries content of about 10 ppm to about 2000 ppm. The composition enables the sheet to be extruded with excellent uniformity.

Abstract: A substrate having the outer surface facing the atmosphere a coating composition having a silicone modified acrylate polymer additive sufficient to allow ease of removing solid particles (dirt) and/or liquids on the surface by reducing the adhesion of such particles and/or liquids to the substrate. The coating composition may also have in combination therewith an ultra violet absorber and/or a mar resistant coating along with a polymer matrix such as an acrylate polymer and a solvent such as methoxypropanol. The amount of silicone modifier acrylate polymer may range from about 0.5 to about 6.0 weight % based on the total weight of the coating composition. A preferred ultra violet absorber is a polybenzoylresorcinol. The preferred substrate is a transparent aromatic polycarbonate resin sheet or multiwall polycarbonate at least two polycarbonate sheets having interdisposed therebetween and joining said sheets a structure of essentially any configuration.
