Propylene polymers and process for the production thereof

Material for semiconductive screening

The invention relates to a process for the preparation of polymers based on polyindoles by chemical polymerization of indole in the presence of an oxidizing agent and of a solvent. The invention also relates to compositions and electroconductive devices containing the polyindoles thus obtained and to the use of the polymers obtained.

Process for the preparation of polyindoles, electroconductive

A polymer mixture, including at least one conductive polymer which has been dedoped to provide at least one dedoped conductive polymer; and at least one polar polymer. The polymer mixture has outstanding dielectric properties so that the polymer mixture is useful for producing electronic, optoelectrical, electrical and electromechanical devices.

Mixtures of polar polymers and dedoped conductive polymers, processes

The invention relates to a process for the preparation of electrically conductive polymers derived from 3-alkylthiophenes by chemical polymerization of the 3-alkylthiophene by means of a ferric salt, an alkyl halide and water. The invention also relates to electrically conductive devices containing the poly(3-alkylthiophenes) obtained and a thermoplastic polymer.

Process for the preparation of electrically conductive polymers derived

The invention relates to a process for the preparation of electrically conducting polymers based on polythiophenes by chemical polymerization of thiophene by means of a ferric salt, an alkyl halide and water. The invention also relates to the electrically conducting devices containing the polythiophenes obtained and a thermoplastic polymer.

Process for the preparation of polythiophenes and electrically

A process for the preparation of a polymer which is electrically conductive and which is based on polythiophene, the process including polymerizing thiophene in a reaction medium including thiophene, from 2.5 to 20 moles of an anhydrous ferric salt per mole of thiophene, from 0.04 to 1 liter of an alkyl halide per gram of thiophene, and from 0.1 to 5% by weight of water introduced into the reaction medium based on the amount of alkyl halide.
