| titleOfInvention | Polyimide film and method for production thereof and method for adjusting isotropy thereof |
| abstract | To provide a polyimide film having an original film width of at least 500 mm, whose isotropy in a width direction is improved to have uniform properties, which polyimide film has been apt to cause property difference in the width direction by continuous molding. n The polyimide film has an original film width of at least 500 mm and a thickness of at most 50 μm, wherein the maximum value of MOR-c is at most 1.35 and a tensile elastic modulus is at least 5.0 GPa at any part of the film. The polyimide film is prepared by the method which comprises steps of: forming a green sheet containing a volatile component, and heating the green sheet by transferring the same through a furnace with both ends of the green sheet being fixed, wherein at the heating step, the original film has an orientation axis angle θ of a positive value at both ends in the original film width direction, and temperature is lower than the boiling point of a main volatile component in a zone where the original film is transferred for a distance equal to the film width between both fixed ends. |
