Abstract[English]
A composition includes specific amounts of a polycarbonate copolymer, a metallic effect additive, and, optionally, a bisphenol A homopolycarbonate. The polycarbonate copolymer can be a copolycarbonate comprising bisphenol A carbonate units and 2-phenyl-3,3-bis(4- hydroxyphenyl)phthalimidine carbonate units, a copolycarbonate comprising bisphenol A carbonate units and bisphenol isophorone carbonate units, a polyestercarbonate including resorcinol iso/terephthalate ester units and resorcinol carbonate units and bisphenol A carbonate units, a polyestercarbonate including sebacic acid-bisphenol A ester units and bisphenol A carbonate units, a polycarbonate-polysiloxane copolymers including bisphenol A carbonate units and polysiloxane carbonate units, a cyanophenol end-capped branched bisphenol A polycarbonate, or a combination thereof. The composition exhibits a desirable balance of metallic visual effects, chemical resistance, and mechanical properties.[French]
L'invention concerne une composition comprenant des quantités spécifiques d'un copolymère de polycarbonate, d'un additif à effet métallique et, optionnellement, d'un homopolycarbonate de bisphénol A. Le copolymère polycarbonate peut être un copolycarbonate comprenant des unités de carbonate de bisphénol A et des unités de carbonate de 2-phényl-3,3-bis(4-hydroxyphényl)phtalimidine, un copolycarbonate comprenant des unités de carbonate de bisphénol A et des unités de carbonate d'isophorone de bisphénol, un polyestercarbonate comprenant des unités d'ester d'iso/téréphtalate de résorcinol et des unités de carbonate de résorcinol et de carbonate de bisphénol A, un polyestercarbonate comprenant des unités d'ester d'acide sébacique-bisphénol A et des unités de carbonate de bisphénol A, un polyestercarbonate comprenant des unités ester d'acide sébacique-bisphénol A et des unités carbonate de bisphénol A, un copolymère polycarbonate-polysiloxane comprenant des unités carbonate de bisphénol A et des unités carbonate de polysiloxane, un polycarbonate de bisphénol A ramifié à coiffe cyanophénolique, ou une combinaison de ceux-ci. La composition présente un équilibre souhaitable d'effets visuels métalliques, de résistance chimique et de propriétés mécaniques.
