Abstract: The invention relates to compounds of the formula in which R and R are halogen atoms and/or Me S groups, where R and R may be identical or different, X is hydrogen, chlorine and/or bromine, Y is sulphoxide, -SO-, and/or sulphone, -SO2-, m is an integer from 2 to 500, n is zero or an integer from 1 to 450, where n + m can be at most 500, with the proviso that the halogen content (from R or R and X) of the compound makes up at least 10 % by weight. These compounds are prepared by reacting compounds of the formula in which R and R are halogen atoms and/or Me S groups, where R and R may be identical or different, X is hydrogen and m is an integer from 2 to 500, with chlorine or bromine in an inert organic solvent or in an aluminium chloride melt, which may contain additives, at elevated temperatures. The compounds of the formula I are used for flameproofing thermoplastics.

Abstract: Molding materials containing high molecular weight polyphenylene ethers are produced by a process in which a solution of a polyphenylene ether in an organic solvent, together with another polymer, is freed of solvent by multi-stage evaporation. The solvent is preferably an aromatic compound from the class comprising the hydrocarbons, halohydrocarbons, ethers or esters, the ratio of the other polymer to the polyphenylene ether is advantageously from 99:1 to 20:80 parts by weight, the other polymer is, in particular, a homopolymer or copolymer of styrene or of a homolog thereof, which may be modified with rubber, and the multi-stage evaporation process preferably comprises not less than two and not more than four working up stages. The evaporation is carried out in general at from 120 DEG to 280 DEG C. and under a pressure of from 1 to 3,000 mbar, advantageously in the presence of assistants which reduce the partial pressure, eg. water and/or methanol.

Abstract: The invention relates to halogen-containing compounds, to a process for the preparation thereof, and to the use of these compounds for flame-proofing thermoplastic synthetic materials. The halogen-containing compounds are described by the following general formula I. where y represents boron, aluminium and antimony, and the radicals and indices have the following significance: Rn: OH, R , R or R where it applies that: R : lower alkyl group or lower haloalkyl group, X: bromine or chlorine, k l: 0 or integers from 1 to 5 and also k + l max. 5; where it applies that: R : lower alkyl group or lower haloalkyl group, Z: bromine or chlorine, s, p: 0 or integers from 1 to 4 and also s + p = max. 4 where Rn, R , Z, s and p have the abovementioned meaning and it also applies that l + p = 1.
