Abstract: The invention relates to a process for the preparation of high-molecular-weight polyphenylene ethers from monohydric phenols containing alkyl substituents, by oxidative coupling reaction with oxygen at temperatures between 10 and 50 DEG C, in the presence of a copper salt/amine catalyst complex and in the presence of an aromatic C6-to C10-hydrocarbon as solvent, where the amine component employed is a diamine of the formula R NH-R -NHR where R and R are tertiary alkyl and/or cycloalkyl groups having 4 to 12 carbon atoms, and R is an alkylene group having 2 to 4 carbon atoms in the connecting chain, in amounts of from 0.1 to 5% by weight, based on the phenol. Suitable amine components are N,N'-di-tert-alkylethylenediamines, in particular N,N'-di-tert-butylethylenediamine.

Abstract: Thermoplastic molding materials contain a copolymer A and a graft copolymer B. The copolymer A is a hard component comprising one or more copolymers of styrene and/or alpha -methylstyrene with from 20 to 40% by weight of acrylonitrile. The graft copolymer B comprises one or more crosslinked acrylate polymer with a mean particle size of 0.5-0.8 mu m (d50 value of the cumulative mass distribution), a particle distribution, expressed by the ratio in the range Q>/=0.6, and a glass transition temperature Tg below 0 DEG C. A mixture of styrene and acrylonitrile in a weight ratio from 88:12 to 65:35 is grafted onto this rubber.

Abstract: Monomer mixts. contg., by wt., (A) 30-80 % mono-vinyl aromatics, (B) 70-20 % acrylic acid, methyacrylic acid, their esters with 1-18C alcohols, maleic anhydride, maleic-,: fumaric-, itaconic-, vinyl phosphonic- and/or vinyl lactic acid, (C) 0-20 % acrylamide, methacrylamide and/or maleimide and (D) 0-10 % copolymerisable cpd. contg. at least 2 ethylenically unsaturated double bonds, are copolymerised continuously, without polymerisation initiators, at 200-400 deg.C.. Pressures above 1 bar are used, under periodic pressure fluctuations with a pressure difference of 15-100 bar and a pressure fluctuation frequency of 6-300/hr. Copolymer use for (i) sizing paper surfaces, (ii) fixing pigments, flame-retardants, optical brighteners and dyestuffs and (iii) coating concrete and wood, is claimed. Water-proofing of surfaces and fixing of organic and/or inorganic additives can take place simultaneously. E.g. paper can be sized and finished with pigments.

Abstract: Surface sizing of paper is carried out with an aq. soln. of a water-soluble salt of a crosslinked copolymer from (a) an 8-12C alpha-olefin, (b) maleic anhydride, methallyl succinic acid, maleic acid semi-ester, acrylic acid and/or methacrylic acid, in molar ratio (a):(b) or 0.9-1.1 to 1.1:0.9 and (c) 0.5-10wt.% based on (a+b) of a difunctional monomer of formula CH2=CR-X-CR=CH2, CH2=C(CH3)-Aryl-C(CH3)=CH2 and/OR (III) (in which R is H, CH3; X is -CO-O-CO- or (II); aryl Viscosity of the aq. soln. is lower than that from known copolymers using divinyl benzene as (C), allowing highly conc. solns. to be used which are still pumpable.
