摘要:
New polymers with K values of from 20 to 140, in which the side chains contain optically active 1,6,6-trimethylnorpinanyl-2-methyl or 3-pinanyl-methyl groups, so that the polymers are also optically active. The polymers are used for the production of coatings and adhesives, as optical modifiers for films, and for finishing paper and textiles.
摘要:
A process for the manufacture of heat-stable, brominated oligostyrenes by brominating selectively hydrogenated oligostyrenes in halogenated solvents in the presence of Lewis acids at from -25.degree. to +20.degree. C. The brominated oligomers are highly heat-stable and can be processed, by themselves or as components of mixtures with other thermoplastics, to give various shaped articles.
摘要:
A paper size comprising a water-soluble salt of a copolymer of from 30 to 85% by weight of olefins of 2 to 12 carbon atoms, having a terminal double bond, and/or vinyl ethers, and from 15 to 70% by weight of basic acrylic and/or methacrylic compounds, which copolymer has a molecular weight of from 600 to 4,500 and is manufactured by continuous copolymerization at from 130.degree. to 320.degree. C.
摘要:
Polymers which have formamide groups in the side branches and which may in addition contain other reactive groups. They can be used to produce moldings, coatings or adhesives.
摘要:
According to the invention, a method for the production of battery electrodes and battery electrodes produced with this method are provided, whereby the method comprises the production of compositions of the electrode materials for cathode or anode material and, if required, a separator material, and the extrusion of the electrode material to form the anode or cathode from the electrode material, and is characterized in that the electrode material comprises isocyanate and an aqueous dispersion of a polymer binder which react with one another to form porous structures. By means of the method according to the invention, extremely elastic and, at the same time, mechanically stable battery electrodes are generated that may be utilized in lithium secondary batteries.
摘要:
Electrodes for high energy lithium polymer batteries are produced. An electrode material mixture of a Li-intercalatable active electrode material, a supporting electrolyte and a solvent is mixed with a binder. Homogenization of the mixture results in a single phase suspension electrode mass which is applied to a conductor to form a homogeneous coating thereon. The electrode mass is adjusted to the desired thickness after drying.
摘要:
Electrically conductive, finely divided pyrrole polymers are prepared by a process in which a pyrrole is polymerized in the presence of a carrier and are used for the production of shaped articles and coatings.
摘要:
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.
摘要:
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.
