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 .ltoreq.1.5 .mu.m and the other part has a mean particle size of .ltoreq.3 .mu.m. Such molding materials not only have good self-extinguishing properties but also give moldings having a particularly uniform matt surface.
摘要:
A thermoplastic molding material which contains two graft copolymers in a matrix of a copolymer based on styrene and acrylonitrile. The first graft copolymer (B) comprising a hard phase prepared from one or more vinyl-aromatic monomers and an elastomer phase, the elastomer phase particles having a diameter of from 0.5 to 5 .mu.m. The second graft copolymer (C) comprising a hard phase and an elastomer phase, said elastomer phase having a bimodal particle distribution in which the diameter of one category of particles is from 0.05 to 0.18 .mu.m and the second category of particles has a mean diameter of from 0.25 to 0.6 .mu.m.
