するものである。Next, an example of a method for manufacturing a polishing belt according to the present invention will be described. In this method, a polyamic acid solution mixed with abrasive grains is applied to the circumferential surface of a cylinder, then heated, the solvent in the solution # applied to the inner circumferential surface of the cylinder is tasted off, and the polyamic acid is converted into an imide. The polyimide tube is converted to form a polyimide tubular material on the inner peripheral surface of the cylinder, and then the tubular material is peeled from the cylinder and then cut to a predetermined width if necessary.

できる。In this method, first, the inner diameter is usually 1 to 50 cm.
A polyamic acid liquid is applied to the inner circumferential surface of a heat-resistant cylinder made of metal, glass, or fluororesin (the inner circumferential surface may be subjected to mold release treatment using silicone resin, fluororesin, etc.). Application of the polyamic acid m solution to the inner circumferential surface of the cylinder is carried out by 1, for example: (a) immersing the cylinder in the polyamic acid solution and pulling it up, 1 then running a bullet-like object, 1 spherical object, etc. inside the cylinder, and (b) the cylinder. (c) Immerse the cylinder in the polyamic acid solution, pull it up at low speed, and hold it directly on the circumferential surface of the cylinder. The method of leaving it still can be done by the temple.

回転させることもできる。In addition, when traveling the bullet-shaped body 1 spherical body etc. as described above, the cylinder is held vertically, horizontally or inclined, but the cylinder can also be rotated in order to make the coating thickness uniform.
また、ポリアミド酸溶液は芳香族テトラカルボン酸２無

- Evaporation of the solvent, which is carried out to remove and convert the polyamic acid into imide.
イミド転化の際に生ずる閉環水等の蒸発等によるボイド
形成を防止するため、約８０〜ｌ ８０ ”Ｃの温度で
約２０〜６０分間加熱して、＃媒を除去し。In order to prevent the formation of voids due to evaporation of ring-closing water, etc. that occurs during imide conversion, the # medium is removed by heating at a temperature of about 80 to 180''C for about 20 to 60 minutes.
次いで約２５０〜３５０℃の温度で約２０〜６０分間加
熱して、閉環水等ｔ−蒸発させると共にイミド転化させ
る方法を採用するのが好適である。It is then preferable to employ a method of heating at a temperature of about 250 to 350° C. for about 20 to 60 minutes to t-evaporate the ring-closing water and convert it into an imide.
