[0075] Hereinafter, although an Example and a comparative example are shown and this invention is concretely demonstrated, this invention is not limited only to an Example.
[0076] In addition, the test methods and materials used in the examples are as follows.
[0077] 1. Test method
[0078] (1) Tensile modulus of elasticity: measured in accordance with JIS K-7162. In addition, the test piece was made into a dumbbell-shaped (Danbell) test piece using Fanatsuku Autotoshito Model 75.
[0079] (2) Maximum point stress: measured in accordance with JIS K-7162.
[0080] (3) Creep resistance: The test piece is made on the side of a rectangle with a length of 100 mm and a width of 10 mm, and two U-shaped notches of 1.5 mm are made on both sides of the central part. A load of 10 kg was applied to one end, and the time until fracture was obtained.
[0081](4) Drop weight test at 0°C: at 0°C, a 5.3R hammer was dropped on the test piece by a Dupon impact testing machine, and the he...
