    摘要: Halogen-containing s-triazine compounds of the formula I ##STR1## where R is OH, R.sup.1, R.sup.2 or R.sup.3, R.sup.1 is ##STR2## where R.sup.4 is lower alkyl or lower haloalkyl, X is bromine or chlorine, k and n are 0 or integers from 1 to 5 and k+n is not more than 5, R.sup.2 is ##STR3## where R.sup.5 is lower alkyl or lower haloalkyl, Z is bromine or chlorine, s and p are 0 or integers from 1 to 4 and s+p is not more than 4, and R.sup.3 is ##STR4## where R, R.sup.5, Z, s and p have the above meanings. The compounds claimed are prepared by reacting cyanuric chloride with a phenol of the formula III ##STR5## and a benzene derivative of the formula IV ##STR6## in the presence of a base. The products thereby obtained are used for flameproofing thermoplastics, in particular styrene/acrylonitrile copolymers made impact-resistant with rubber (ABS resins).

    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.
