Novel polycarbonate resins, process for production of said resins, and compositions containing said resins

摘要

Novel polycarbonate resins, a process for production of said polycarbonate resins, and compositions containing said polycarbonate resins and glass fibers as major components are disclosed. The polycarbonate resins have: (1) a repeating unit (I) represented by the general formula (A): <IMAGE> and a repeating unit (II) represented by the general formula <IMAGE> (all the symbols are as defined in the appended claims); (2) a pentahalogenophenoxy group as the end group thereof; and (3) a viscosity average molecular weight of at least 5,000. The polycarbonate resins are excellent in all of flame retardance, fluidity, impact resistance and transparency. Thus the polycarbonate resins and compositions containing them are useful for production of, e.g., moldings for which all the above characteristics are required.
