- - REINFORCED POLYESTERCARBONATE POLYCARBONATE-POLYDIORGANOSILOXANE POLYBUTYLENE-TEREPHTHALATE BLEND AND ARTICLE COMPRISING SAME

摘要

The composition comprises a specific amount of poly (butylene terephthalate), a reinforcing filler, and a polycarbonate comprising a copolyester carbonate and a polycarbonate-polydiorganosiloxane block copolymer. The copolyester carbonate includes aliphatic ester groups. These compositions, which exhibit a desirable melt flow rate and ductility balance, are particularly useful for forming thin plastic parts of consumer electronic devices, particularly mobile telephones.
