The present invention provides polycarbonates and copolycarbonates with a higher glass transition temperature and hence also use temperature and improved metal adhesion, processes for their production and their use for producing blends, moldings and extrudates obtainable therefrom. The invention further provides novel bisphenols and their use for preparing (co)polycarbonates.

La présente invention concerne des polycarbonates et des copolycarbonates qui présentent une température de transition vitreuse plus élevée et donc une température d'utilisation plus élevée ainsi qu'une meilleure adhérence sur les métaux, des procédés pour leur fabrication et leur utilisation pour la préparation de mélanges et de pièces moulées et des produits d'extrusion obtenus à partir de ceux-ci. L'invention concerne en outre de nouveaux bisphénols et leur utilisation pour la préparation de (co)polycarbonates.
