▎ 摘 要
NOVELTY - Polymer composition comprises 0.1-99 wt.% polycarbonate copolymer and homopolymer or its blend, 0.1-70 wt.% crystalline polyester, 0.1-50 wt.% inherently dissipative polymer and 0.001-10 wt.% transesterification inhibitor, where the polymer composition exhibits a surface resistivity less than 1/* 109Ohms when measured in accordance with ASTM D257, and the combined weight percent value of all components does not exceed about 100 wt.%, and all weight percent values are based on the total weight of the polymer composition. USE - The polymer composition is useful for manufacturing articles including personal computers, notebook and portable computers, cell phone antennas and communication equipment, medical applications, radio-frequency identification applications, and automotive applications, and as a computer and business machine housing such as a housing for high end laptop personal computers, monitors, robotics, a hand held electronic device housing (such as a housing or flash holder for smart phones, tablets, music devices),electrical connectors, LED heat sink, and components of lighting fixtures, wearables, ornaments, and home appliances. ADVANTAGE - The polymer composition is free of or substantially free of carbon fiber, conductive carbon black, graphite, graphene, carbon nanotubes, or carbon nano-structures, has sufficiently low surface resistivity (at least as low as 1/*109Ohms), and maintains colorable appearance.
