Abstract:
A curable composition comprising: at least, (A) a hydrocarbon compound having a plurality of carbon-carbon double bonds, wherein a silyl group is added to at least a part of the carbon-carbon double bonds; and (B) a carbonaceous material. There is provided a curable composition capable of providing a cured product having a high electro-conductivity, which is excellent in thermal resistance, electro-conductivity, moldability (such as those in compression molding, transfer molding, injection molding and injection compression molding), and in particular, excellent in hydrothermal resistance.
Abstract:
An object of the present invention is to provide a fluorinated polymer of adequate molecular weight with excellent transparency in a wavelength range from visible to near infrared, and to also provide a method of producing such a polymer. The present invention provides a fluorinated polymer comprising a structure represented by a formula (1) as a structural unit, (1) as well as a method of producing this polymer using a corresponding tetrafluoroxylylenediamine or a tetrafluoroxylylene glycol as a raw material.
