The Young ' s modulus of the l mil " Myla ゼ ' Cpolyester 且1m was measured in a frequency range of 100 to 4000 c / s as a function of temperature , together with the study of the symptom of dependency on directions of the film. The frequency dependence of the Young ' s modulus has been found to be almost inappreciable , 1t has also been found that the ウalues of the Young ' s modulus in dyne/ cm2 are 5. 2 × 1010 at 15°Cand 3 . 3 × 1010 at 90℃ in the maximum direct置 on , while 42xIO1°at 15°C and 2
