It originally has a low glass transition temperature and has problems with dimensional stability against heat, which has hindered the expansion of its uses. Additionally, the crystallization rate is much higher than that of other polymers, such as polyesters such as polyethylene terephthalate, making the stretching process difficult. This tendency is particularly noticeable in the production of biaxially stretched films, where non-uniform stretching tends to occur, causing so-called necking and an imbalance in performance in the machine and transverse directions.

下であることが好ましい。Next, amorphous thermoplastic polyamide (1) is an amorphous thermoplastic polyamide having a higher T g than crystalline thermoplastic polyamide (7i), but the requirement for the T g value is due to the following reason. That is, crystalline thermoplastic polyamide (A)
This is to improve the dimensional stability of a film or fiber made of an IH compound of amorphous thermoplastic polyamide (11) and amorphous thermoplastic polyamide (11) by increasing the Tg. Further, the requirement that it be amorphous is due to the need to appropriately slow down crystallization in manufacturing processes such as melt film forming, melt spinning, and stretching to improve processability. Therefore, polyamides that are amorphous but have a low Tg, or polyamides that are crystalline even if they have a high Tg, are undesirable, and even if they are actually attempted, they will cause problems in either dimensional stability or productivity. There are many cases. And crystalline thermoplastic polyamide (A

。(Examples 1 to 3, Comparative Example 1) Copolytetramethylene adipamide (symbol A, melting point 2
90°C1T g 83°C) and the polyamide of the above-mentioned reference example (symbol B) were melt-mixed at 300°C in various proportions as shown in Table 1, extruded through a 1゛ die, and heated at 5°C.
Rapidly cooled with C casting roller to a thickness of approximately 100 mm.
An unstretched film of μ was obtained. This unstretched film was stretched at a temperature of 120°C at a magnification of 3.0 times in length and 3.0 times in width using a simultaneous two-wheeled stretching device with one tenter type, and then
A constant length heat treatment was carried out at 30°C to obtain a medium 400° stretched film. The stretching speed was 20 m/l1in.
