また組成物−■を用いてプレス温度２６０℃、プレス圧
力８０ ｋｇ ／ ｃｄで厚み４００μｍのフィルムを
プレス成形した。In addition, a film with a thickness of 400 μm was press-molded using the composition-① at a press temperature of 260° C. and a press pressure of 80 kg/cd.
該フィルムを用いて２３５℃で同時２軸延伸を行ったと
ころ、延伸倍率３×３の２軸延伸フイルムを得ることが
できた。When this film was subjected to simultaneous biaxial stretching at 235° C., a biaxially stretched film with a stretching ratio of 3×3 could be obtained.
