A process is proposed for coagulation of an aqueous polymer dispersion, which comprises, during or after the coagulation, converting the dissolved coagulation salt into an insoluble form.

Thermoplastic molding materials based on polyphenylene ethers, nylons

High molecular weight polyphenylene ethers are prepared from monohydric phenols by a conventional polycondensation, by a method in which the resulting polymers are reacted with an epoxide of the general formula (I) ##STR1## where R.sup.1 and R.sup.2 can be identical or different and are each alkyl, cycloalkyl, aryl, aryloxy, alkoxy or carboxyalkyl, each of which may contain a further epoxide group, or C.sub.3 -C.sub.20 -alkyl-substituted amino, or R.sup.1 is hydrogen and R.sup.2 is one of the above groups, or R.sup.1 and R.sup.2 form part of a cycloalkyl ring.

Poly (phenylene ethers) and their preparation

A thermoplastic molding material consists of from 10 to 90 parts by weight of a polycarbonate A and from 90 to 10 parts by weight of a graft copolymer B having a mean particle size of from 200 to 700 nm (d.sub.50 value of the integral mass distribution). The graft polymer B is formed from an elastomer (rubber) (b.sub.1), which accounts for from 10 to 80% by weight, and a grafted shell (b.sub.2), which accounts for from 90 to 20% by weight, the percentages in each case being based on (B). The elastomer (b.sub.1) is composed of from 50 to 99.9% by weight of an alkyl acrylate, where alkyl is of 1 to 8 carbon atoms, and from 0.1 to 5% by weight of a copolymerizable polyfunctional crosslinking monomer. The grafted shell (b.sub.2) is produced in three stages and contains, as graft monomers,

A thermoplastic molding material consists of a polycarbonate A and a graft copolymer B, the latter consisting of an elastomer (rubber) (b.sub.1) and a shell (b.sub.2) grafted onto the elastomer. The elastomer (b.sub.1) contains, as copolymerized units, from 35 to 100% by weight of a diene from the group consisting of the conjugated dienes of 4 to 5 carbon atoms, and can contain, as copolymerized units, from 0 to 65% by weight of a monomer from the group consisting of the alkyl acrylates or alkyl methacrylates, where alkyl is of 1 to 8 carbon atoms. The shell (b.sub.2) is obtained in a conventional manner by successive polymerization of the monomers constituting the shell, in two process steps, in the presence of the elastomer (b.sub.1); in a first process step, from 10 to 90% by weight of a mixture of a vinylaromatic hydrocarbon and one or more ethylenically unsaturated monomers which differ from the said hydrocarbon, in a weight ratio of from 90:10 to 60:40, are first incorporated as copolymerized units, followed by the polymerization of from 90 to 10% by weight of a monomer from the group consisting of the alkyl acrylates or of the alkyl methacrylates, where alkyl is of 1 to 8 carbon atoms. The molding material is used for the production of shaped articles.
