stabilizer is added at an amount of 0 01 to 0 5 preferably 0 01 to 0 2 relative to the weight of the composition the stabilized compositions of the invention may contain other conventional additives which are known for their art recognized functions these include dyes flame retardants and hydrolysis and uv stabilizers plasticizers and mold release agents in one preferred embodiment the composition is suitable for making highly transparent optical storage devices the invention is further illustrated but is not intended to be limited by the following examples in which all parts and percentages are by weight unless otherwise specified stabilized compositions in accordance with the invention have been prepared and their properties determined the polycarbonate used in all the examples shown below was a homopolycarbonate based on bisphenol a having a melt flow rate of 75 g 10 min the noted additives were as follows these were incorporated in the composition at the indicated levels noted as pph parts by weight per one hundred parts of resin the table presented below summarizes the results of an evaluation whereby the optical properties of polycarbonate compositions containing the stabilizer and ester of the invention were compared to corresponding compositions containing but one of these additives the results point to that the desirable combination of low yellowness index and low haze is a characteristic.
