Abstract[English]
An ultrasonically weldable part comprising improved weld strength and chemical resistance comprises a thermoplastic composition comprising a poly(carbonate-siloxane) composition comprising: a poly(carbonate-siloxane) comprising 30 to 70 wt% siloxane repeating units present in an amount effective to provide less than 6 wt% siloxane repeating units, based on the total weight of the thermoplastic composition, or a poly(carbonate-siloxane) comprising 30 to 70 wt% siloxane repeating units and a poly(carbonate-siloxane) comprising 2 wt% to less than 30 wt% siloxane repeating units, optionally, a polycarbonate, and optionally an additive composition, wherein the siloxane domain of a molded sample of the thermoplastic composition has an average diameter of 70 nm or less, measured using atomic force microscopy.[French]
L'invention concerne une pièce soudable par ultrasons présentant une résistance de soudure et une résistance chimique améliorées et qui comprend une composition thermoplastique comprenant une composition de poly(carbonate-siloxane) comprenant : un poly(carbonate-siloxane) comprenant 30 à 70 % en poids de motifs répétés de siloxane présents en quantité efficace pour fournir moins de 6 % en poids de motifs répétés de siloxane, sur la base du poids total de la composition thermoplastique, ou un poly(carbonate-siloxane) comprenant 30 à 70 % en poids de motifs répétés de siloxane et un poly(carbonate-siloxane) comprenant de 2 % en poids à moins de 30 % en poids de motifs répétés de siloxane, éventuellement un polycarbonate, et éventuellement une composition d'additif, le domaine siloxane d'un échantillon moulé de la composition thermoplastique présentant un diamètre moyen inférieur ou égal à 70 nm, mesuré par microscopie à force atomique.
