Abstract: Process for producing composite articles made of polyesters and elastomers. Composite articles made of a thermoplastic polyester and a vulcanizate are to be produced. These articles are obtained by producing the vulcanizate under conventional vulcanization conditions in contact with the hard component by vulcanization of a rubber composition which contains the following components:I. 100 parts by weight of a rubber,II. From 0 to 300 parts by weight of fillers,III. From 1 to 10 parts by weight of peroxidic vulcanization agents,IV. From 0 to 4 parts by weight of vulcanization activators andV. From 0 to 150 parts by weight of plasticizers, wherea) the hard and/or the soft component, as desired, additionally contains from 0.5 to 12 parts by weight of a difunctional or polyfunctional maleimide andb) in the case of the hard component containing no difunctional or polyfunctional maleimide, the rubber possesses carboxyl or acid anhydride groups.A strong composite is obtained by this process.

Abstract: The invention describes a process for the production of a composite article of at least two component pieces, firmly bonded to one another, of a vulcanized rubber compound on the one hand and a polyamide composition on the other hand, the vulcanized rubber compound being prepared under customary vulcanization conditions in contact with the polyamide composition by vulcanization of a rubber compound which comprises the following components:I. 100 parts by weight of a rubber,II. 0 to 300 parts by weight of fillers,III. 0 to 150 parts by weight of plasticizer,IV. 1 to 10 parts by weight of peroxide vulcanization agent,V. 0 to 4 parts by weight of vulcanization activators andVI. 1 to 10 parts by weight of a silane containing double bonds.

Abstract: Latex foam molded articles are prepared using a plastic mold heated by means of microwave energy. The molded article can be readily released from the mold. The mold has good dimensional accuracy and a long serviceable lifetime. The walls of the mold are composed of a molding composition which has the following constituents:a) 20 to 100 parts by weight of polyphenylene ether,b) 0 to 30 parts by weight of styrene polymers,c) 0 to 30 parts by weight of impact-modifying additives,d) 0 to 40 parts by weight of reinforcing agents and/or fillers ande) 0 to 15 parts by weight of additives.The mold surface is passivated. Compared with conventional processes for the production of latex foam molded articles, the cycle time and the energy consumption are considerably reduced when this mold is used.

Abstract: A fiber-reinforced molding composition, comprising:a) 97 to 50% by weight, relative to the sum of (a) and (b), of a mixture of 30 to 100 parts by weight of a polyphenylene ether, 0 to 70 parts by weight of a styrene polymer, 0 to 10 parts by weight of a polyoctenylene and 0.1 to 2.5 parts by weight of an .alpha.,.beta.-unsaturated carboxylic acid derivative or a precursor thereof;b) 3 to 50% by weight of carbon fibers and/or glass fibers whose surfaces bear functional groups which are capable of entering into chemical coupling reactions with the .alpha.,.beta.-unsaturated carboxylic acid derivatives; and optionallyc) dyes, pigments, plasticizers, flame retardant additives, processing auxiliaries, other customary additives or combinations thereof.

Abstract: A thermoplastic moulding material is prepared by the admixture ofa) 3 to 80 parts by weight of polyphenylene ethers,b) 20 to 97 parts by weight of polyamides,c) 0.1 to 10 parts by weight of carbonates of the general formula ##STR1## in which X and Y independently of one another denote an alkyl, cycloalkyl, aryl or substituted aryl radical, each having up to 12 C atoms,d) 0 to 30 parts by weight of impact modifiers ande) 0 to 75 parts by weight of further polymers, if necessary.

Abstract: Molding compounds based on polyphenylene ethers, which are distinguished by reduced combustibility and good processing properties. The molding masses contain (A) 100 parts by weight polyphenylene ether, (B) 1 to 40 parts by weight of a dibenzyl toluene and, relative to the total weight of the molding compound, (C) 0 to 30% reinforcing material, and (D) 0 to 5% additives. The molding compounds are used for the production of technical articles such as pipes, plates and housings.
