Abstract:
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.
