SELF-EXTINGUISHING THERMOPLASTIC MOLDING MATERIAL

摘要

Self-extinguishing molding materials, comprising (A) a polymer of a vinyl-aromatic compound, especially a styrene polymer, which has been made impact-resistant, (B) a polyphenylene ether and (C) a flameproofing additive, with or without (D) conventional additives, wherein one part of the soft component of the impact-resistant polymer of the vinyl-aromatic compound has a mean particle size of ? 1.5 .mu.m and the other part has a mean particle size of >3 .mu.m. Such molding materials not only have good self-extinguishing properties but also give moldings having a particularly uniform matt surface.
