An object of the present invention is to provide an insulated wire which includes an insulating layer with a low relative permittivity and has excellent heat resistance and excellent abrasion resistance. The insulated wire of the present invention includes a conductor (A), and an insulating layer (B) formed on the periphery of the conductor (A), the insulating layer (B) is formed from a resin composition that contains a resin (I) with a relative permittivity of 3.0 to 4.0 and a fluororesin (II).

Insulated wire

The present invention aims to provide a resin composition which can provide a molded article excellent in insulation and showing a low relative permittivity and which causes no melt fracture even when extrusion-molded at a high shear rate. The resin composition of the present invention includes an aromatic polyether ketone resin (I) and a fluororesin (II). The fluororesin (II) is a copolymer of tetrafluoroethylene and a perfluoro ethylenically unsaturated compound represented by the following formula (1):CF&#x2550;CF&#x2014;Rf&#x2003;&#x2003;(1)wherein Rfrepresents &#x2014;CFor &#x2014;ORf; and Rfrepresents a C1-C5 perfluoroalkyl group. The aromatic polyether ketone resin (I) and the fluororesin (II) satisfy a melt viscosity ratio (I)/(II) of not lower than 0.001 but lower than 0.3.

Thermoplastic resin composition, and molded article thereof

The present invention aims to provide a resin composition capable of providing a molded article which is excellent in flexibility, acid resistance, and electrical properties. The resin composition of the present invention includes: an aromatic polyether ketone resin (I); and a fluororesin (II), the fluororesin (II) being a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1): CF&#x2550;CF&#x2014;Rf(1) wherein Rfrepresents &#x2014;CFor &#x2014;ORf, and Rfrepresents a C-Cperfluoroalkyl group, the fluororesin (II) being dispersed as particles in the aromatic polyether ketone resin (I), the resin composition satisfying a ratio (I):(II) by mass between the aromatic polyether ketone resin (I) and the fluororesin (II) of 50:50 to 10:90.

Resin composition and molded article

Provided is a method for easily and safely removing, from a reactor, a catalyst used in a reaction that is performed using hydrogen fluoride in the presence of the catalyst. In a reaction performed in a reactor containing at least hydrogen fluoride and a catalyst, the catalyst is removed through a process comprising a heating step of performing heat-treatment so that the ambient temperature of the reactor is 80&#xb0; C. or more after completion of the reaction, and a purge step of flowing inert gas into the reactor to discharge the hydrogen fluoride to the outside of the reactor after completion of the reaction.

Method for removing catalyst used in reaction

The present invention provides a process for producing a fluoroolefin by reacting, in a gas phase, a fluorinating agent and a chlorine-containing alkene or a chlorine-containing alkane in the presence of at least one catalyst selected from the group consisting of chromium oxide, at least part of which is crystallized, and fluorinated chromium oxide obtained by fluorinating the chromium oxide. According to the present process, a target fluoroolefin can be obtained at a high conversion rate of the starting material and with high selectivity.

Process for producing fluorine-containing olefin

This invention provides a process for producing a fluoroolefin comprising reacting, in a vapor phase, a fluorinating agent and a chlorine-containing alkene or a chlorine-containing alkane in the presence of at least one catalyst selected from the group consisting of chromium oxide containing a Group 5 element and fluorinated chromium oxide containing a Group 5 element. According to the process of the present invention, the target fluoroolefin can be obtained with high starting material conversion and good selectivity.
