TRANSPARENT THERMOPLASTIC COMPOSITIONS HAVING HIGH FLOW AND DUCTILIY, AND ARTICLES PREPARED THEREFROM |
摘要 |
<p>Disclosed herein is a thermoplastic composition comprising a combination of: a polysiloxane-polycarbonate copolymer and a poly(aliphatic ester)-polycarbonate copolymer comprising soft block ester units of the formula (8a); wherein m is 4 to 18, wherein the thermoplastic composition has a melt volume rate of 14 cc/10 min to 22 cc/10 min at 300°C and under a load of 1.2 Kg and a dwell time of 6 minutes, according to ASTM D1238-04, wherein an article molded from the thermoplastic composition and having a thickness of 3.2 mm has a percent transmittance of greater than 85% according to ASTM D1003-00, and wherein 100% of a set of five test articles each having a thickness of 3.2 mm and molded from the thermoplastic composition exhibit ductile fracture at -40°C when measured for notched Izod Impact according to ASTM D256-04. An article comprising the thermoplastic composition is also disclosed.</p> |
