Disclosed herein too is a method for manufacturing a multilayered sheet comprising melt blending a composition comprising a thermoplastic polymer and an IR absorbing additive to produce a core layer; melt blending a composition comprising a thermoplastic polymer and an ultraviolet radiation absorber to produce a first cap layer; combining the core layer with the first cap layer in such a manner that the cap layer is disposed upon and in intimate contact with a surface of the core layer.

A thermoplastic composition is described, based on a copolycarbonate which includes at least two structural units. Structure I is usually a conventional carbonate based on bisphenol A, while structure II is a bisphenol carbonate which includes branched or linear groups extending from a bridging carbon atom or carbon group which connects two aromatic rings. The compositions exhibit very good melt flow, along with enhanced shear-thinning behavior. These characteristics are important for optical disc applications. Thus, related articles are described, along with processes for preparing such articles.

Copolycarbonates containing such structural units as birefringence-reducing or &ldquo;soft block&rdquo; units are prepared by conducting a reaction, such as melt polymerization or equilibration, between a precursor polycarbonate and a monomer, polycarbonate oligomer or high molecular weight polycarbonate which is a source of other structural units. The crystallinity of the resulting precursor copolycarbonate or one of the reagents employed in its preparation is enhanced and the precursor copolycarbonate is subjected to solid state polymerization.
