摘要:
The present invention performs special heat treatment on a polymer film in a temperature range from (i) a lower limit to temperature rise being equal to or higher than a starting temperature of thermal decomposition of the polymer film, i.e., which is a temperature observed at an early stage of the thermal decomposition of the polymer film, to (ii) an upper limit to temperature rise being equal to or lower than an intermediate temperature of thermal decomposition of the polymer film. This reduces foaming in the film during graphitization treatment following the special heat treatment. Thus, even with a higher heating rate for graphitization, it is possible to produce a graphite film having good quality.

Disclosed herein is a method for producing an elongated (rolled) carbonaceous film by polymer pyrolysis while suppressing the fusion bonding of the carbonaceous film. The method for producing a carbonaceous film includes the step of heat-treating a polymer film wound into a roll, wherein the heat treatment is performed after the polymer film is wound into a roll to have a gap between adjacent layers of the polymer film at a temperature lower than a pyrolysis onset temperature of the polymer film so that the roll of polymer film as a whole satisfies a relationship that a value obtained by dividing a thickness of a gap between adjacent layers of the polymer film (Ts) by a thickness of the polymer film (Tf) (Ts/Tf) is 0.16 or higher but 1.50 or lower. As a method for forming gaps between the layers of the polymer film, a method in which the polymer film is wound into a roll together with a slip sheet and then the slip sheet is removed can be used, which is effective at suppressing the fusion bonding of a carbonaceous film.

A graphite film with fewer wrinkles and/or undulations is obtained providing two or more stages of heating space and carrying out continuous baking. Especially when a cooling space is provided between each of the heating spaces and another, a graphite film can be obtained which is excellent in flatness and has a high thermal diffusivity.

摘要:
A reaction between epoxy-terminated polyamide and an acid anhydride compound can yield a modified polyamide resin, into resin skeleton of which carboxy groups to react with epoxy resin are introduced. An adhesive agent having excellent heat-resistance can be provided by the use of a composition of this modified polyamide resin and epoxy resin. Furthermore, an adhesive tape for a semiconductor device having excellent properties can be produced by laminating the adhesive agent and the protective layer on one surface of an organic insulated film.
