POLYCARBONATE COMPOSITION WITH LOW STATIC PERFORMANCE
The present invention provides a process for reducing static charge in a polycarbonate part involving combining a polycarbonate and a diphosphite to form a composition and molding a part from the composition, wherein the part exhibits reduced static charge compared to a part made without addition of the diphosphite.
1 . A process for reducing static charge in a polycarbonate part comprising: combining a polycarbonate and a diphosphite to form a composition; and
molding a part from the composition,
wherein the part exhibits reduced static charge compared to a part made without addition of the diphosphite.
2 . The process according to claim 1 , wherein the diphosphite comprises bis(2,4-dicumylphenyl)pentaerythritol diphosphite.
3 . The process according to claim 1 , wherein the diphosphite is included in an amount of from about 0.04% by weight to about 0.4% by weight based on the weight of the composition.
4 . The process according to claim 1 , wherein the part comprises an automobile headlight lens.
5 . A composition made by a process comprising combining a polycarbonate and a diphosphite to form a composition, wherein a part made from the composition exhibits reduced static charge compared to a part made from a composition without addition of the diphosphite.
6 . A part made by the process according to claim 1 .
