Abstract
Disclosed herein are processes for preparing articles from compositions including a cross-linked polycarbonate. The cross-linked polycarbonate may be derived from a polycarbonate having about 0.5 mol % to about 5 mol % endcap groups derived from a monohydroxybenzophenone. The article is molded, then exposed to UV radiation. A plaque including the composition can achieve a UL94 5VA rating.
