Polyanils

Polyacetylene which is modified by reaction with a dienophilic compound, preparation of the said polyacetylene and its use for the production of moldings by processing by a thermoplastic method.

Modified polyacetylene

A highly conductive polyacetylene film is obtained by orienting a catalyst-containing polyacetylene film or an essentially catalyst-free polyacetylene film which has been swelled in a solvent after the catalyst has been washed out, the polyacetylene being essentially free of sp.sup.3 -hybridized carbon atoms.

Process for producing highly conductive polyacetylene film

Impact resistant thermoplastic molding materials containing a styrene polymer modified with rubber to be impact resistant, a hydrogenated styrene containing block copolymer and a polyphenylene ether as well as optional additives in which 50 to 98 percent by weight of the particles of the flexible component of the impact resistant styrene polymer have an average particle diameter of equal to or less than 1.0 micron and 2 to 50 percent by weight of the particles of the flexible have an average particle diameter of equal to or greater than 2 microns.

Impact resistant thermoplastic molding materials

In an optical recording medium of the reflection type, the light-absorbing layer contains polypyrrole as the light-absorbing substance.

Optical recording medium

Composites of electrically conductive materials and inorganic binders contain, as the electrically conductive material, a p- or n-doped electrically conductive polymer which possesses conjugated bonds and forms a coherent phase.

Composites of conductive polymers and inorganic binders

Electroconductive coats are applied by a process wherein the anode and the cathode of an electrolysis bath are composed of carbon fibers, filaments or sheetlike structures therefrom and the electrolyte solution contains a monomer and a conductive salt, the monomer being oxidized at the anode and deposited on the anode as a polymer and the conducting salt used containing a metal as cation, so that the metal is reduced and deposited on the cathode.

Electrochemical coating of carbon fibers

Electrically conductive layers are applied on to carbon fibers or filaments or sheet-like structures of these by a process in which monomers from the class consisting of the anilines or of the pyrroles or thiophenes are polymerized on the surface of the carbon structures in the presence of an electrolyte.

Coating carbon fibers

A layer of electrically conductive polymers is applied by a process in which carbon fibers of filaments or sheet-like structures of carbon fibers or filaments are coated with sulfonic acids of phthalocyanines or porphyrins, the filaments treated in this manner are made the anode in a solution which contains monomers from the class consisting of the 5-membered heterocycles, and the monomers are anodically polymerized so that a conductive layer is formed on the fibers, filaments or sheet-like structures.

Polyphenylene ethers are prepared 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.degree. 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, by a method in which the conversion of the phenols is carried out in two more reaction zones, in which some or all of the solvent, the catalyst complex and the phenols and, where relevant, the activator is initially taken and is circulated by means of a conveying unit, 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.
