    • The invention relates to electric engineering and can be used for producing a converter for converting an internal action into electric signal: strain-gauge elements, pressure sensors and button switches in the form of electric signal switching elements. The aim of said invention is to develop a electroactive polymer material exhibiting a high sensitivity to the electrocunductivity of the external actions, for example to a pressure, etc within a wide range of polymer film thicknesses and a high reproducibility of useful properties. The inventive electroactive polymer whose electrical activity depends on the action of external physical fields comprises molecular fragments having a high polarizability and/or a bistable electronic energy structure with respect to an excess electron capture process. Said molecular fragments are bound therebetween through the intermediate elements of a molecular chain. The electroactive molecular fragments form a single macromolecular structure chemically bound through the molecular chains. The material based on said electroactive polymer is embodied in the form of films or fibres or coatings or bodies of rotation. At least one geometrical size defining a material form is equal or less than the double penetration depth of a surface charge.

    • The present invention discloses noncrystalline dibenzofuran polymers composed of repeating units represented by formula (II) and having a molecular weight corresponding to a reduced viscosity of at least 0.2 dl/g as measured for the 0.5 % (W/V) N-methylpyrrolidone solution thereof at 25 DEG C, and a method of producing the same (II). Also disclosed are dibenzofuran copolymers composed of both the repeating units represented by formula (II) and a specified proportion of at least one kind of repeating units represented by general formula (III) and having a molecular weight corresponding to a reduced viscosity of at least 0.2 dl/g as measured for the 0.5 % (W/V) concentrated sulfuric acid solution thereof at 25 DEG C, and a method of producing the same, wherein A represents -O-, -CO-, -S-, -SO2-, an alkylene group or a single bond, and n is 0, 1 or 2. Further disclosed are benzofuran derivatives useful as the starting material of the aforementioned polymers and copolymers, and a method of producing these derivatives. The obtained noncrystalline polymers and copolymers are excellent in the stability during molding and have reduced polarity and hygroscopicity, so that they are useful as the molding material for various applications.
