Description
1. 下記化学式(1A)で表される繰り返し単位と、下記化学式(2A)で表される繰り返し単位とを含むことを特徴とするポリイミド前駆体。
式中、Xは芳香環を含まない4価の基であり、R1、R2、R3、R4はそれぞれ独立に水素、炭素数1〜6のアルキル基、または炭素数3〜9のアルキルシリル基である。)
前記化学式(2A)で表される繰り返し単位の含有量が、全繰り返し単位に対して、10〜90モル%であることを特徴とする前記項1又は前記項2に記載のポリイミド前駆体。
式中、Xは芳香環を含まない4価の基であり、R1、R2、R3、R4はそれぞれ独立に水素、炭素数1〜6のアルキル基、または炭素数3〜9のアルキルシリル基である。)
前記化学式(2)で表される繰り返し単位の含有量が、全繰り返し単位に対して、10〜90モル%であることを特徴とする前記項6又は前記項7に記載のポリイミド。
式中、Xは芳香環を含まない4価の基であり、R1、R2、R3、R4はそれぞれ独立に水素、炭素数1〜6のアルキル基、または炭素数3〜9のアルキルシリル基である。)
本発明のポリイミド前駆体は、溶媒中でテトラカルボン酸成分としてのテトラカルボン酸二無水物とジアミン成分とを略等モル、好ましくはテトラカルボン酸成分に対するジアミン成分のモル比[ジアミン成分のモル数/テトラカルボン酸成分のモル数]が好ましくは0.90〜1.10、より好ましくは0.95〜1.05の割合で、例えば120℃以下の比較的低温度でイミド化を抑制しながら反応することによって、ポリイミド前駆体溶液組成物として好適に得ることができる。
テトラカルボン酸二無水物を任意のアルコールと反応させ、ジエステルジカルボン酸を得た後、塩素化試薬(チオニルクロライド、オキサリルクロライドなど)と反応させ、ジエステルジカルボン酸クロライドを得る。このジエステルジカルボン酸クロライドとジアミンを−20〜120℃、好ましくは−5〜80℃の範囲で1〜72時間攪拌することで、ポリイミド前駆体が得られる。80℃以上で反応させる場合、分子量が重合時の温度履歴に依存して変動し、また熱によりイミド化が進行することから、ポリイミド前駆体を安定して製造できなくなる可能性がある。また、ジエステルジカルボン酸とジアミンを、リン系縮合剤や、カルボジイミド縮合剤などを用いて脱水縮合することでも、簡便にポリイミド前駆体が得られる。
あらかじめ、ジアミンとシリル化剤を反応させ、シリル化されたジアミンを得る。必要に応じて、蒸留等により、シリル化されたジアミンの精製を行う。そして、脱水された溶剤中にシリル化されたジアミンを溶解させておき、攪拌しながら、テトラカルボン酸二無水物を徐々に添加し、0〜120℃、好ましくは5〜80℃の範囲で1〜72時間攪拌することで、ポリイミド前駆体が得られる。80℃以上で反応させる場合、分子量が重合時の温度履歴に依存して変動し、また熱によりイミド化が進行することから、ポリイミド前駆体を安定して製造できなくなる可能性がある。
1)の方法で得られたポリアミド酸溶液とシリル化剤を混合し、0〜120℃、好ましくは5〜80℃の範囲で1〜72時間攪拌することで、ポリイミド前駆体が得られる。80℃以上で反応させる場合、分子量が重合時の温度履歴に依存して変動し、また熱によりイミド化が進行することから、ポリイミド前駆体を安定して製造できなくなる可能性がある。
