  • Process for the preparation of modified polycarbonate molding compositions
    Patent number: 4367186
    Abstract: This development is concerned with an improved process of preparing polycarbonate molding compositions and molded articles having superior hydrolysis resistance, stress crack resistance and flame retardancy, by thermoplastically processing a partially crosslinked aromatic polycarbonate. A crosslinkable aromatic thermoplastic polycarbonate is subject to irradiation to cause crosslinking on its surface such that between about 5 and 50 wt. % of the polymer is crosslinked and it is then thermoplastically processed. This partially crosslinked polycarbonate may be blended with uncrosslinked thermoplastic aromatic polycarbonate or known flame retardant agents. This development is also concerned with the compositions or articles so produced.
