摘要/描述

Potassium diphenyl sulfonate (SSK), poly-(sulfonyl phenylene phosphonate) (PSPPP), and their mixtures are proved to be effective flame-retardants for polycarbonates (PCs) by measuring the limited oxygen index values and UL-94 of blends. The flame-retardant systems are characterized by thermogravimetric analysis under dynamic conditions. The resulting data, together with the analysis of the activation energies, demonstrates that the additives ac-celerate thermodegradation, especially in the early stage, and different additives cause a different process in the final stage.
