    Abstract: The invention relates to a thermoplastic molding material which contains a mixture of (I) from 95 to 5% by weight of a polyphenylene ether and (II) from 5 to 95% by weight of a copolymer consisting of A1) from 78 to 99 parts by weight of a monovinylaromatic compound, A2) from 1 to 12 parts by weight of (meth)acrylic acid and B) from 0 to 20 parts by weight of an elastomer component which has a glass transition temperature of ? 0.degree. C, the sum of the number of parts by weight being 100. This molding material processes appropriately high heat distortion resistance, good resistance to chemicals and well balanced mechanical properties.

    Abstract: Thermoplastic molding materials which contain a copolymer which has been made impact-resistant with a rubber. The copolymer is produced by polymerizing a mixture of a monovinyl-aromatic compound and an acrylic acid derivative or methacrylic acid derivative in the presence of a rubber. The folding materials contain a specific proportion of soft component. The diameter of the particles of the soft component, and the swelling index of the soft component, lie within a specific range, and the tensile strength of the molding material is higher than the yield strength.

    Abstract: Impact-resistant polystyrene having improved surface properties is made by first polymerizing styrene in which is dissolved a substantially uncrosslinked rubber, and then mechanically mixing the product with a crosslinked or crosslinkable rubber. Up to 35% of the styrene in the first stage of the process may be replaced by a comonomer, e.g. acrylonitrile, alkylstyrenes and halostyrenes. The examples describe polymerizing styrene with: (1) a butadiene-styrene copolymer, and mixing the product with a butadiene-styrene copolymer, (2) a butadiene-styrene copolymer, and mixing the product with a butadiene-butyl fumarate copolymer, (3) cis-1,4-polybutadiene, and mixing the product with a butadiene-butyl fumarate copolymer, (4-5) acrylonitrile, a butylacrylate-acrylonitrile copolymer and cis-1,4-polybutadiene, and mixing the product with a butadiene-acrylonitrile copolymer.

    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.
