REINFORCED POLYESTERCARBONATE, POLYCARBONATE-POLYDIORGANOSILOXANE, POLY(BUTYLENE-TEREPHTHALATE) BLEND, AND ARTICLE COMPRISING SAME

摘要

A composition includes specific amounts of a poly(butylene terephthalate), a reinforcing filler, and a polycarbonate that includes a copolyestercarbonate and a polycarbonate-polydiorganosiloxane block copolymer. The copolyestercarbonate includes aliphatic ester groups. The composition, which exhibits a desirable balance of melt flow and ductility, is especially useful for forming thin plastic parts of consumer electronic devices, including mobile phones.
