Abstract

Flame-retardant polycarbonates have been produced by addition of metal sulfonate compounds. However, the process is to be validated for thin-walled products. In this study, to improve flame retardancy of polycarbonate, an ionic liquid was additionally added. With a decrease in the second combustion time, a small quantity of the ionic liquid as less as 0.05 phr was enough to effectively meet the UL94 V0 protocol. Thermogravimetric experiments showed that the maximum weight loss rate increased with addition of the ionic liquid, indicating the sudden decomposition of polycarbonate. This sudden decomposition increased the rate of formation of char components during flaming, resulting in improvement of flame retardancy of polycarbonate.
