Cross-linked polycarbonate resin with improved chemical and flame resistance

摘要

Disclosed herein are 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. A plaque including the composition can achieve a UL94 5VA rating. Also disclosed herein are articles including the compositions, methods of using the compositions, and processes for preparing the compositions.

1. A composition having improved flame resistance comprising:
a cross-linked polycarbonate, the cross-linked polycarbonate derived from a non-cross-linked polycarbonate with an endcap content that consists of endcap groups derived from a monohydroxybenzophenone, wherein the endcap content is about 0.5 mol% to about 5 mol% of the non-cross-linked polycarbonate; and a flame retardant; wherein the composition does not comprise an impact modifier; wherein a plaque formed from the composition achieves a UL94 5VA rating at a thickness of 1.5 ±10% mm or less.
