ポリアミド樹脂の極限粘度[η]は、ポリアミド樹脂0.5gを96.5%硫酸溶液50mlに溶解させ、得られた溶液の、25℃±0.05℃の条件下での流下秒数を、ウベローデ粘度計を使用して測定し、「数式:[η]=ηSP/(C(1+0.205ηSP))」に基づき算出した。
[η]:極限粘度(dl/g)
ηSP:比粘度
C:試料濃度(g/dl)
t:試料溶液の流下秒数(秒)
t0:ブランク硫酸の流下秒数(秒)
ηSP=(t-t0)/t0
ポリアミド樹脂の融解熱量(ΔH)は、JIS K 7122(2012年)に準じて、1回目の昇温過程での結晶化の発熱ピークの面積から求めた。
1-1.ポリアミド樹脂の合成
(合成例1)
テレフタル酸259.5g(1561.7ミリモル)、1,6-ジアミノヘキサン118.9g(1023.1ミリモル)、ビスアミノメチルノルボルナン(三井化学ファイン株式会社製)85.0g(551.1ミリモル)、次亜リン酸ナトリウム一水和物0.37gおよび蒸留水81.8gを内容量1Lのオートクレーブに入れ、窒素置換した。190℃から攪拌を開始し、3時間かけて内部温度を250℃まで昇温させた。このとき、オートクレーブの内圧を3.0MPaまで昇圧させた。このまま1時間反応を続けた後、オートクレーブ下部に設置したスプレーノズルから大気放出して、低次縮合物を抜き出した。その後、この低次縮合物を室温まで冷却後、低次縮合物を粉砕機で1.5mm以下の粒径まで粉砕し、110℃で24時間乾燥させた。
オートクレーブに入れたテレフタル酸の量を162.2g(976.1ミリモル)とし、さらに85.6g(585.7ミリモル)のアジピン酸を入れ、1,6-ジアミノヘキサンの量を182.9g(1574.2ミリモル)とし、ビスアミノメチルノルボルナン(三井化学ファイン株式会社製)を入れなかった以外は合成例1と同様にして、ポリアミド樹脂2を得た。ポリアミド樹脂2の極限粘度[η]は0.8dl/g、融点(Tm)は320℃、ガラス転移温度(Tg)は95℃、融解熱量(ΔH)は48mJ/mgであった。
