Abstract[English]
Compositions include: (a) from about 55 wt% to about 89 wt% of a polycarbonate- polysiloxane copolymer; (b) from about 0.01 wt% to about 30 wt% of (i) a polycarbonate homopolymer or (ii) a cycloaliphatic polyester; and (c) from about 8 wt% to about 25 wt% of a reinforcing filler. A specimen including the composition and having a thickness of at least 2 millimeters (mm) exhibits a transmission of at least 80% as tested with a hazemeter in accordance with ISO 14782 and ISO 13468. Methods of forming the compositions are also described.[French]
Les compositions comprennent : (a) d'environ 55 % en poids à environ 89 % en poids d'un copolymère polycarbonate-polysiloxane ; (b) d'environ 0,01 % en poids à environ 30 % en poids de (i) un homopolymère de polycarbonate ou (ii) un polyester cycloaliphatique ; et (c) d'environ 8 % en poids à environ 25 % en poids d'une charge de renforcement. Un échantillon comprenant la composition et ayant une épaisseur d'au moins 2 millimètres (mm) présente une transmission d'au moins 80 % telle que testée avec un hazemètre selon les normes ISO 14782 et ISO 13468. L'invention concerne également des procédés de formation des compositions.
