各重合体のガラス転移温度(Tg)は、示差走査熱量測定装置(Rigaku社のDSC装置「Thermo Plus DSC8230」)を用いて、窒素雰囲気下、昇温速度20℃/分で得られたサーモグラムのDSC昇温曲線において、ベースラインと変曲点での接線との交点に対応する温度とした。上記変曲点は、DSC昇温曲線の微分曲線であるDDSC曲線におけるピークに対応する温度とした。また、DSCのベースラインの確認には、適宜DDSC曲線を参照した。
各重合体の1%質量減少温度(Td1)は、差動型示差熱天秤(SIIナノテクノロジー社の「TG/DTA6200」)を用いて、窒素雰囲気下、昇温速度10℃/分の条件で得られた熱質量曲線から、重合体の質量が累計で1質量%減少した時の温度とした。なお、Td1は、耐熱性の指標の1つであり、その値が大きいほど耐熱性に優れると評価できる。
各重合体の各種有機溶媒に対する溶解性は、各重合体を表1に示す各種有機溶媒にそれぞれ濃度10質量%となるように加え、攪拌した後、目視で沈殿物を確認できなかった場合を「A」、目視で沈殿物を確認できた場合を「B」として評価した。
EDM:ジエチレングリコールエチルメチルエーテル
MMP:3-メトキシプロピオン酸メチル
BuOAc:酢酸ブチル
PGMEA:プロピレングリコール-1-モノメチルエーテル-2-アセテート
GBL:γ-ブチロラクトン
まず、適量の各重合体を塩化メチレンに溶解させて重合体溶液を調製し、この溶液をガラス板上にキャスト成膜し、常圧下、室温で一晩乾燥させた。次いで真空乾燥機にて残存する塩化メチレンを除去し、寸法3×4cm、平均厚み90μmのフィルムを得た。得られたフィルムの一方の面に、真空蒸着装置(日本電子社の「JEE-420」)を用いてアルミニウムを真空蒸着することにより電極を形成し、εr及びtanδを評価するための試験片を得た。この試験片について、JIS-C-2138(2007年)に準拠し、プレシジョンLCRメーター(ヒューレット・パッカード社の「4284A型」)を用いて、振幅100mV、周波数1MHz、温度25℃及び相対湿度50%の条件によりεr及びtanδを測定した。
