Zusammenfassung:	Disclosed herein are polysiloxane-polycarbonate copolymer articles. In one embodiment, a 1/8th inch thick bar formed from the thermoplastic composition has a B-Y ratio of less than or equal to about 1.75. This article, which has a dimension that is greater than or equal to 1.5 cm, comprises the thermoplastic composition which comprises a polysiloxane-polycarbonate copolymer, wherein the copolymer comprises repeating diorganosiloxane units of formula (1): wherein each R is, independently, a C1-13 monovalent organic group; and E has an average value of 20 to 35.
