Problems solved by technology

[0002] There are two processing modes for traditional conductive and flame-resistant PPO alloys, one is based on conductive carbon black, and the other is based on metal oxides. The amount of addition is large, the conductivity is low, the physical performance is poor, and the pollution is extremely serious; although the amount of the latter is small, the quality is large, and the metal oxide is an inorganic substance, and the combination with the organic substance is poor, resulting in a sharp drop in performance, and there are serious deficiencies.
