Title (DE) SCHLAGZÄHMODIFIZIERTE POLYCARBONAT-ZUSAMMENSETZUNGEN
(EN) IMPACT STRENGTH MODIFIED POLYCARBONATE COMPOUNDS
(FR) COMPOSITIONS DE POLYCARBONATE À RÉSILIENCE MODIFIÉE
Abstract:
(DE) Die vorliegende Erfindung betrifft schlagzähmodifizierte Polycarbonat-Zusammensetzungen enthaltend ein erstes Pfropfpolymerisat auf Basis von Silikonacrylat-Komposit-Kautschuk als Pfropfgrundlage, wobei der Anteil an Silikonkautschuk 65 - 95 Gew.-% (bezogen auf die Pfropfgrundlage) beträgt, und ein zweites Pfropfpolymerisat, welches freies, d.h. nicht chemisch an den Kautschuk gebundenes Copolymer mit einem gewichtsgemittelten Molekulargewicht von 60000 bis 150000 g/mol enthält, die Verwendung der Polycarbonat-Zusammensetzungen zur Herstellung von Formkörpern und die Formkörper selbst. Die erfindungsgemäßen Zusammensetzungen und Formmassen weisen eine optimale Kombination aus guter Reißdehnung, guter Hydrolysebeständigkeit und niedriger Schmelzeviskosität auf.
(EN) The present invention relates to impact strength modified polycarbonate compounds comprising a first graft polymer based on silicon acrylate composite rubber as a graft basis, wherein the proportion of silicone rubber is 65 - 95 % by weight (relative to the graft basis), a second graft polymer comprising free copolymer, that is, not bonded to the rubber, having a weight-averaged mean molecular weight of 60000 to 150000 g/mol, to the use of the polycarbonate compounds for producing molded parts, and to the molded parts themselves. The compositions and molding compounds according to the invention comprise an optimal combination of good elongation at rupture, good hydrolysis resistance, and low melting viscosity.
(FR) La présente invention porte sur des compositions de polycarbonate à résilience modifiée, contenant un premier polymère greffé à base de caoutchouc composite silicone acrylate en tant que base de greffage, la fraction de caoutchouc silicone représentant 65 - 95 % en poids (par rapport à la base de greffage), et un second polymère greffé, lequel contient un copolymère libre, c'est-à-dire non chimique lié au caoutchouc avec une masse moléculaire moyenne en poids de 60 000 à 150 000 g/mole. L'invention porte également sur l'utilisation des compositions de polycarbonate pour la fabrication de corps moulés et sur les corps moulés eux-mêmes. Les compositions et matières moulées de l'invention comprennent une combinaison optimale de bon allongement à la rupture, bonne résistance à l'hydrolyse et faible viscosité à l'état fondu.
