摘要

Polycarbonate with improved mechanical properties and tu00c9rmicas, as well as coefficient of thermal dilatau00c7u00e7o reduced. The present invention relates to polycarbonates thermoplastic with high glass temperature, as well as the masses to shape that are distinguished by improved thermal properties, especially by thermal expansion is reduced.In addition, the present invention relates to a process for the production of polycarbonates.This invention relates especially to polycarbonates, to the structural unit, which derives from phthalimide of the formula (1) as well as the compositions of polycarbonate and molding masses for these, as well as a process for the production of polycarbonates, as well as to their use, especially as a Reflectors and substrates of displays.
