In an embodiment, a method for the manufacture of an injection molded article in an injection mold comprises at least one flow length of at least 50 cm, the flow length being defined as the shortest distance between a point of injection in the mold and an inner mold wall, the method comprising injection molding a polycarbonate composition comprising an aromatic polycarbonate, from 0.01 wt. % to 0.30 wt. % based on the weight of the polycarbonate composition of an epoxy additive having at least two epoxy groups per molecule, and from 0.01 wt. % to 0.30 wt. % based on the weight of the polycarbonate composition of a phenolic diphosphite derived from pentaerythritol.

Use of a polycarbonate composition

A process for manufacturing a polycarbonate composition includes melt polymerizing a dihydroxy compound and a carbonate compound in the presence of a catalyst to form a polycarbonate; and adding 1 to 400 ppm of glycerol tristearate to form the polycarbonate composition, wherein the polycarbonate composition is unquenched.

Polycarbonate composition to produce optical quality products with high quality and good processability

In an embodiment, a method for making a thermoplastic composition, comprising: melt polymerizing a polycarbonate, extruding and melt filtering the polycarbonate to form a melt filtered polycarbonate; forming the thermoplastic composition comprising the melt filtered polycarbonate, 0.03 to 0.05 wt % of a triacylglyceride release agent; and 0.10 to 0.14 wt % of a UV stabilizer; wherein the weight percentages are based on the total weight of the composition; and extruding the thermoplastic composition.

Enhanced polycarbonate extrusion grades

The present disclosure relates to thermoplastic compositions, methods of making thermoplastic compositions, and articles made from thermoplastic compositions. The disclosed compositions comprise a polycarbonate polymer, a triacylglyceride release agent, and a monoacylglyceride release agent. In an embodiment, the thermoplastic composition comprises: greater than 90 weight percent based on the total weight of the composition of a melt polycarbonate polymer; a triacylglyceride release agent; and a monoacylglyceride release agent. The total amount of triacylglyceride release agent and the monoacylglyceride release agent is 0.01 to 0.5 weight percent based on the total weight of the composition.

Polymer blends suitable for use in optical article. The polymer blends comprise a first and second polycarbonate and have properties particularly suited for use in high density optical data storage media.

Data storage media containing clear polycarbonate blends

This invention relates to data storage media, and more particularly to data storage media having both a data storage layer and an adjacent transparent overlayer wherein the data storage layer is capable of reflecting an energy field incident upon said transparent overlayer prior to being incident upon said data layer. Specifically, this invention relates to data storage media having thin transparent polyestercarbonate overlayers.

Data storage medium containing polyestercarbonate

It has been discovered that the shape of a resin pellet can be controlled to reduce cycle time of an injection molding machine and improve the yield by narrowing variability in the plasticizing time.
