Abstract: Compositions formed from a blend of polycarbonate/siloxane copolymer, polycarbonate, and polycyclohexylenedimethylene terephthalate are disclosed that provide superior performance in terms of notched Izod impact, glass transition temperature (Tg), strength after aging, ability to withstand secondary processing conditions, and in other respects. Such compositions exceed critical-to-quality requirements for use in manufacturing components for electronic communication devices.
