Abstract
PURPOSE: To obtain film excellent in smoothness and uniformity of thickness, by a method wherein the title polymer having a specific melt viscosity is melted, extruded on a cooling medium at a specific temperature in the form of film, stretched uniaxially under special conditions and then stretched in the orthogonal direction and fixed thermally.
CONSTITUTION: The titled polymer wherein the content of constitutional unit of the formula is at least 90mol% and the melt viscosity at 300°C is 100W600,000 poise under a shear rate 200/sec is melted and extruded on a cooling medium having a surface temperature 120°C or less in the form of film. The film obtained by such a method having a density 1,320W1,330 is stretched 3W4.7 times at 85W100°C in a uniaxial direction, then 2.7W4.5 times at 87W110°C in the direction at right angles to the uniaxial stretching direction and then fixed thermally at 200W275°C.
