B法:ポリカルボジイミドを他の成分と予め混合し、ホッパーから一括投入した。
これに対して、比較例1は、ポリカルボジイミドの配合割合は実施例1と同じであるが、他の成分と共に一括投入しているため、熱可塑性ポリエステルエラストマーの末端基をポリカルボジイミドで十分に封鎖できず、酸価を十分に低下させることができず、△MFRが高くなりすぎた。その結果として、平滑性に劣り、押出成形性に劣っていた。また、耐熱性・耐熱老化性にも劣っていた。
比較例2は、ポリカルボジイミドを過剰に配合しているため、未反応のポリカルボジイミドが残留しており、ゲル化が生じて増粘したため、△MFRが低くなりすぎ、成形初期から押出成形性が不安定であった。また、ポリカルボジイミドを他の成分と共に一括投入しているため、ポリカルボジイミドを過剰に配合したにもかかわらず、局所的な増粘が進みやすくなり、その結果として、押出成形性に劣っていた。
比較例3は、ポリカルボジイミド(B-1)を全く配合していないため、酸価を十分に低下させることができず、MFR及び△MFRが高くなりすぎた。その結果として、押出成形がそもそも不可能であった。
比較例4は、ポリカルボジイミド(B-1)をほとんど配合していないため、その他の点では実施例1と同様であるにもかかわらず、酸価を十分に低下させることができず、△MFRが高くなりすぎた。その結果として、平滑性に劣り、押出成形性に劣っていた。また、耐熱性・耐熱老化性にも劣っていた。
比較例5は、多官能グリシジル化合物(B′-1)を過剰に配合することでゲル化が生じたため、MFRが低くなりすぎた。その結果として、押出成形がそもそも不可能であった。
比較例6は、熱可塑性ポリエステルエラストマーとしてソフトセグメントが脂肪族ポリカーボネートではなく脂肪族ポリエーテルであるもの(A-2)を使用しているため、その他の点では実施例1と同様であるにもかかわらず、耐熱性・耐熱老化性に劣っていた。
