Abstract
(DE)
Verfahren zur Herstellung stabilisierter Polyester/Polycarbonatblends, wobei man A) 40 bis 99,9 Gew.-% eines Polyesters und B) 0,1 bis 60 Gew.-% eines phosphorhaltigen Stabilisators in der Schmelze mischt, austrägt, abkühlt und granuliert und die so erhaltene Komponente A' anschließend mit einem Polycarbonat C) sowie gegebenenfalls einem Polyester A) und einem kautschukelastischen Polymerisat D) sowie gegebenenfalls weiteren Zusatzstoffen E) mischt.
(EN)
The invention relates to a method for producing stabilized polyester/polycarbonate blends, whereby; A) 40 to 99.9 wt. % of a polyester and B) 0.1 to 60 wt. % of a stabilizer containing phosphorous are mixed in the melt, are removed, cooled, and granulated, and component A' which is obtained in this manner is subsequently mixed with a polycarbonate C), is optionally mixed with a polyester A) and a rubber elastic polymerizate D), and is optionally mixed with additional additives E).
(FR)
L'invention concerne un procédé de préparation de mélanges stabilisés de polyester/polycarbonate, selon lequel, on mélange A) à la matière fondue entre 40 et 99,9 % en poids d'un polyester et B) entre 0,1 et 60 % en poids d'un stabilisant à base de phosphore, qui en sont ensuite extraits, refroidis et granulés. Les constituants A' ainsi obtenus sont ensuite mélangés avec un polycarbonate C) ainsi qu'éventuellement un polyester A) et un polymérisat D) à élasticité de caoutchouc, et éventuellement avec d'autres additifs E).
