ポリマーの数平均分子量は、ゲル浸透クロマトグラフィ-(GPC)によって測定した。より具体的には、溶媒として臭化リチウム0.01mol/Lを含むN,N-ジメチルホルムアミドを用い、装置として屈折率検出器〔日本分光(株)製、品番:RI-2031 Plus〕および紫外線検出器〔日本分光(株)製、品番:UV-2075 Plus〕を備えたGPC測定装置〔カラム:昭和電工(株)製、商品名:Shodex KD-802.5と商品名:Shodex KD-804とを連結〕で測定した。なお、外部標準としてポリメチルメタクリレート(分子量:1450、2000、8000、20000、80000、200000、800000または1000000g/mol)を使用した。
(1)示差走査熱量測定(DSC)
示差走査熱量測定は、示差走査熱量測定装置〔セイコーインスツル(株)製、商品名:EXSTAR DSC6100〕を用い、窒素ガス雰囲気中にて25~300℃の温度で10℃/minの昇温速度で行なった。その結果に基づいてポリマーのガラス転移温度またはポリマーの融点を求めた。
熱重量分析は、熱重量分析装置〔セイコーインスツル(株)製、品番:SSC/5200SII〕を用い、窒素ガス雰囲気中で10℃/minの昇温速度で25~800℃の温度で行なった。また、熱重量分析の結果に基づき、5%重量損失温度または10%重量損失温度を決定した。なお、5%重量損失温度は、試料(ポリマー)の質量が5%減少したときの温度を意味し、10%重量損失温度は、試料(ポリマー)の質量が10%減少したときの温度を意味する。
フィラメントの引張強度は、繊維径が約200μmであり、長さ40mmのフィラメントを用い、引張試験機〔インストロン(INSTRON)社製、品番:3365-L5)にて室温で1mm/secのクロスヘッド速度で引っ張ることにより、フィラメントが破断するまでの最大強度を測定した。フィラメントの破断時の伸びは、フィラメントの引張強度を測定し、フィラメントが破断するときのフィラメントが伸びた長さを求め、当該伸びた長さをフィラメントの元の長さで除し、100倍したときの値である。ヤング率は、応力-ひずみ曲線の初期傾きによって求めた。
靭性は、前記で得られた応力-ひずみ曲線においてフィラメントが破断したときに描かれる領域の面積に等しいことから、当該領域を積分することによって面積を求めた。
