摘要:
A process for the preparation of electrically conductive polymers by polymerizing acenaphthylene, N-vinyl-heterocyclics, eg. N-vinylcarbazole or N-vinylpyridine, or N,N-divinylaniline at from -80.degree. to +100.degree. C. in the presence of a cationtic catalyst, wherein from 1 to 50 percent by weight of an oxidizing Lewis acid, preferably FeCl.sub.3, FeBr.sub.3, SbCl.sub.5, SbF.sub.5, AsF.sub.5 or CF.sub.3 -SO.sub.3 H, or a combination of AlCl.sub.3 or TiCl.sub.4 with the said compounds or with CrO.sub.3 or OsO.sub.4 is used as the catalyst. In a preferred embodiment of the process, thin films of the monomers to be polymerized, applied to glass or to a polymeric base, preferably to a plastic film, are treated with gaseous SbCl.sub.5, SbF.sub.5 or AsF.sub.5. The conductive polymers obtained can be used in the electrical industry for the production of solar cells, for the conversion and fixing of radiation and for the production of electrical and magnetic switches, as well as for the antistatic treatment of plastics.

摘要:
The present application relates to a method of performing living cationic polymerization of monomers by supermolecular anion-binding catalysis. It uses various simple Bronsted acids or adducts thereof with a monomer as the cationic initiator, and various hydrogen bond donors as the catalyst for binding and dissociating counter anions dynamically, to living and controlled polymerize one or more cationically polymerizable monomers to form a homopolymer or a copolymer. In the present application, the hydrogen-bond donor can exert non-covalent anion-binding interactions to dynamically and reversibly activate dormant covalent bond under mild conditions, in turn to precisely control the equilibrium between dormant covalent precursors and active cationic species, thereby achieving the precise control of the polymer's molecular weight, distribution and end group structure, and solving the environment-unfriendly relevant problems in traditional metal-based Lewis acid catalysis, which include extreme low polymerization temperature, restrict anhydrous requirement of the reaction, strict purification requirement of the monomer and catalysis-initiating system, metal residue in polymer or the like.

摘要:
A photoconductive iodinated poly(vinyl carbazole) having a mole ratio of iodine to vinyl carbazole between 0.05 and 0.9. The iodinated poly(vinyl carbazole) is used to form a photoconductive layer or coating on a substrate such as a transparent substrate or paper. The iodinated poly(vinyl carbazole) is formed by reacting a slurry of poly(vinyl carbazole) having a high surface area, typically above about 10 m.sup.2 /gram, with a source of iodide and of iodate ions.
摘要:
Polymeric compositions comprising the product of the addition polymerization of N-vinylcarbazole and at least one member selected from the group consisting of N-vinylphthalimide and the isostructural modifications thereof. Many of the above polymeric products are photoconductive and, thus, are suitable for use in electrophotography.
