Abstract[English]
A polycarbonate composition, including 10-80 weight percent (wt%) of a homopolycarbonate, a poly(phthalate-carbonate), or a combination thereof; 10-30 wt% of a bromine-containing polycarbonate copolymer; 5-60 wt% of a poly(carbonate-siloxane), present in an amount effective to provide 1-10 wt% of total siloxane, based on the total weight of the polycarbonate composition; 5-30 wt% of a glass-containing reinforcing agent; optionally, up to 10 wt% of a mineral filler; optionally, an organophosphorous flame retardant in amount effective to provide up to 1.5 wt% of phosphorous, based on the total weight of the polycarbonate composition; and optionally, up to 10 wt% of an additive, wherein the amount of homopolycarbonate, poly(phthalate-carbonate, bromine-containing polycarbonate copolymer, poly(carbonate-siloxane), glass-containing reinforcing agent, optional mineral filler, optional organophosphorous flame retardant, and optional additive total 100 wt%.[French]
La présente invention concerne une composition de polycarbonate, comprenant de 10 à 80 pour cent en poids (% en poids) d'un homopolycarbonate, d'un poly(phtalate-carbonate), ou d'une combinaison associée ; de 10 à 30 % en poids d'un copolymère de polycarbonate contenant du brome ; de 5 à 60 % en poids d'un poly(carbonate-siloxane), présent en une quantité efficace pour fournir de 1 à 10 % en poids de siloxane total, sur la base du poids total de la composition de polycarbonate ; de 5 à 30 % en poids d'un agent de renforcement contenant du verre ; éventuellement jusqu'à 10 % en poids d'une charge minérale ; éventuellement un ignifugeant organophosphoré en une quantité efficace pour fournir jusqu'à 1,5 % en poids de phosphore, sur la base du poids total de la composition de polycarbonate ; et éventuellement, jusqu'à 10 % en poids d'un additif, la quantité d'homopolycarbonate,de poly(phtalate-carbonate), de copolymère de polycarbonate contenant du brome, de poly(carbonate-siloxane), d'agent de renforcement contenant du verre, de charge minérale facultative, d'ignifugeant organophosphoré facultatif et d'additif facultatif total étant de 100 % en poids.
