ーの―点より少なくとも約４０℃低いのが好ましい。A particularly preferred plastic deformation process consists of stretching the polymer to a stretch ratio of at least 15, preferably at least about 20. Of course, the stretching tension is less than the tensile strength of the polymer, but the elongation of the polymer is greater than that which would occur by flow stretching, which is sufficient to produce the necessary alignment. It is necessary to do so. Preferably, the processing elongation temperature) i is at least about 40°C below the - point of the polymer.

101 ON/m2 or more, if VC Yotte Vl at least 6 X 101 ON1 m2 of polymer can be obtained. Since the Young's modulus of supramolecular substances depends on the measurement method, in this specification, the Young's modulus is defined as the deviation of 0.1% at 21°C by the Detsudo Roding creep test.
The elastic modulus when the stress is measured by maintaining it for a second is defined as the foot. This test method was developed by Gupta and Ward: Journal
of Macromolecular Science and Physics B1.373 (1967).

Although molecular orientation is generally uniaxial, it is also possible to obtain a biaxially oriented polymer material by employing an appropriate stretching method. The presence of essentially perfect orientation can be confirmed by physical measurements such as X-ray diffraction or nuclear 1 magnetic resonance. A simple test is performed by determining the weight loss of the polymer in fuming nitric acid, kTAU, which is 61 ribs over the entire life of the molecule. If the weight loss is small, the trade will be completed in one lifetime.
