ABSTRACT:
UV-stabilized or other modified polycarbonates are prepared by combining polycarbonate, a radical polymerization initiator and a UV-stabilizer-molecule or other additive such as a flame retardant or IR additive containing a reactive group susceptible to radical attack in a melt. In the melt, the UV-stabilizer or other additive is graft polymerized to the polycarbonate to form a modified polycarbonate. The method can be practiced using bis-phenol-A (BPA) polycarbonates, soft-segment polycarbonates and high heat polycarbonates. The reaction may be performed in an extruder.
