    • Disclosed is a transparent multilayer article comprising a core layer comprising a thermoplastic carbonate polymer; a first layer comprising a carbonate thermoplastic polymer and an infrared (IR) absorbing additive; and a second layer comprising a thermoplastic carbonate polymer and a ultraviolet (UV) absorbing stabilizer, wherein the first layer does not contain an UV absorbing additive and the second layer does not contain an IR absorbing additive. Disclosed herein too, is a method for manufacturing a transparent multilayer article comprising melt blending a first thermoplastic carbonate polymer composition to produce a core layer; melt blending a second thermoplastic carbonate polymer composition with an IR absorbing additive to produce a first layer; and melt blending a third thermoplastic carbonate polymer composition with an UV absorbing stabilizer; combining the core layer, first layer, and second layer such that the first layer is disposed between the core layer and the second layer such that a first surface of the first layer is in intimate contact with a first surface of the core layer and a second surface of the first layer is in intimate contact with a first surface of the second layer.
    • 公开了一种透明多层制品,其包含含有热塑性碳酸酯聚合物的芯层; 包含碳酸酯热塑性聚合物和红外(IR)吸收添加剂的第一层; 和包含热塑性碳酸酯聚合物和紫外线(UV)吸收稳定剂的第二层,其中第一层不含UV吸收添加剂,第二层不含IR吸收添加剂。 本文也公开了一种用于制造透明多层制品的方法,包括熔融共混第一热塑性碳酸酯聚合物组合物以制备芯层; 将第二热塑性碳酸酯聚合物组合物与IR吸收添加剂熔融共混以产生第一层; 并将第三热塑性碳酸酯聚合物组合物与UV吸收稳定剂熔融共混; 结合所述芯层,第一层和第二层,使得所述第一层设置在所述芯层和所述第二层之间,使得所述第一层的第一表面与所述芯层的第一表面紧密接触, 第一层的表面与第二层的第一表面紧密接触。
