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 workingup stages. The evaporation is carried out in general at from 120 to 280.degree.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: A process for the preparation of high molecular weight polyphenylene ethers from monohydric phenols which have alkyl substituents in both ortho-positions and may additionally have an alkyl substituent in one meta-position but not in the para-position, by an oxidative coupling reaction, employing oxygen, at from 10 to 25.degree.C, in the presence of a catalyst complex comprising a copper salt and an N-substituted imidazole, in the presence of an aromatic C8-C10-hydrocarbon solvent. N-Methylimidazole, N-ethylimidazole, N-isopropyl-imidazole, N-n-butylimidazole, N-cyclohexylimidazole, N-octylimidazole and N-phenylimidazole are preferably used as the imidazole, advantageously in amounts of from 0.5 to 5 percent by weight.

Abstract: The invention relates to a thermoplastic molding material of an elastomeric polymer A, a shell B grafted to the polymer A, and a copolymer C as rigid matrix. The amount of polymer A is 1 to 25 percent by weight based on the weight of A + B + C. It has a glass transition temperature, Tg, of less than 0.degree.C and an average particle size of 200 to 500 nanometers ( d50 value of the integral mass distribution) and is composed of: 50 to 99.9 percent by weight of at least one alkylacrylate with 1 to 8 carbon atoms in the alkyl radical and 0.1 to 5 percent by weight of a polyfunctional monomer which has a crosslinking action. Grafting shell B represents 5 to 40 percent by weight based on A + 9 + C and is composed of at least one of the monomers of the group of b1 ) vinylaromatic monomers, and b2 ) the ethylenically unsaturated monomers. Grafting shell B is prepared in two stages with 30 to 10 percent by weight of the monomers b1 being used in the first stage, and 30 to 70 percent by weight of a mixture of monomers b1 and b2 in a weight ratio of 90:10 to 60:40 being used in the second stage. Copolymer C is added in an amount of 35 to 94 percent by weight based on A + B + C and consists of a vinylaromatic monomer and an ethylenically unsaturated monomer. The molding material may contain commonly used additives in effective amounts and is used for the prepara--tion of molded parts.

Abstract: Disclosed is a process of preparation of polyphenylene ethers from monohydric phenols, which possess alkyl substituents in the two ortho-positions and, if desired, in the meta-position, but not in the para-position, by an oxidative coupling reaction with oxygen at from 15 to 50.degree.C and under from 1 to 10 bar in the presence of a catalyst complex, of a solvent and, if required, of an activator. In this process,the conversion of the phenols is carried out in two or more reaction zones. Some or all of the solvent, catalyst complex phenols and where relevant, activator are initially added to one of the reaction zones and are circulated in the other reaction zone and about 60-100% of the stoichiometric amount of oxygen required for the oxidative coupling is introduced into the first reaction zone and from 0 to about 40% of the said stoichiometric amount is introduced into the second reaction zone. This process is interesting in that it makes it possible to carry out oxidative coupling of phenols with oxygen in a very economic and reliable manner, with very high space-time yields, formation of only a small amount of by-products, and minimum emissions of gas and volatile components.

Abstract: High molecular weight polyphenylene ethers are prepared from monohydric phenols by an oxidative coupling reaction with oxygen in the presence of a solvent and of a catalyst complex consisting of a copper salt and an organic amine of the general formula where R1 is C2-C20-alkylidene, preferably C2-C12-alkylid-ene, or alkenylidene, R2 is H or C1-C12-alkyl, preferably C1-C4-alkyl, or C5-C8-cycloalkyl, each of which is unsubstituted or substituted by functional groups, and n is an integer from 1 to 4, preferably 1 or 2. Preferred functional groups are -OR3, -NHR3 or -SR3, in which R3 is H C1-C12-alkyl or C5-C8-cycloalkyl, and the most suitable amines are 3-tert.-butoxypropylamine, 4-tert.-butoxy-butylamine, 3-tert.-butoxy-2-methylpropylamine, 3-tert.-butoxy-2,3-dimethylpropylamine, 3-tert.-butoxy-2-methyl-octylamine and N-methyl-N-(4-tert.-butoxybutyl)-amine. The polyphenylene ethers can be processed to moldings by a thermoplastic method.
