Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: a cross-linkable polycarbonate resin comprising about 0.5 mole % to about 5.0 mole % endcap groups derived from a monohydroxybenzophenone, wherein the cross-linkable polycarbonate resin is made from an interfacial polymerization process comprising the steps of: (i) forming a mixture comprising bisphenol-A, a monohydroxybenzophenone, and a tertiary amine catalyst in a water-immiscible solvent and water solvent system; (ii) stirri…
