PAAを脱塩水中で水和し、水酸化ナトリウム水溶液を添加してPAA溶液のpH値を6に調整した。次いで、1−エチル−3−(3−ジメチルアミノプロピル)カルボジイミド塩酸塩(EDAC、Sigma Aldrich社)を添加した。室温で20分間撹拌した後、アミノアルキルチオールを添加し、pHを6に再調整した。次いで、反応混合物を撹拌下に室温で24時間反応させた。生じた反応生成物を透析で単離した。沈殿したポリマーを濃水酸化ナトリウム溶液中に溶解し、中和し、次いで透析した。
ポリアクリル酸(PAA)とアリルアミンとの類似のポリマー反応のための一般的手順
PAAを15mLのDMFに60℃で溶解し、アリルアミンを添加した。ジシクロヘキシルカルボジイミドを、1mLのDMFに溶解し、ポリマー溶液に添加した。溶液を60℃で24時間撹拌した。溶液を真空下で濃縮し、ポリマーを酢酸エチル中で沈殿させた。アリルアミンの転換率は1H−NMR分光法で判定した。
1H−NMR[ppm]:δ(500MHz、DMSO−D6)=1.32〜1.9(CH2);2.1〜2.5(CH);5〜5.2(CH2=CH);7.99(1 OH)
調製例3〜5と同様に、PAAを15mLのDMF中に60℃で溶解し、アリルアミンを添加して、12%の転換率を達成した。ジシクロヘキシルカルボジイミドを、1mLのDMFに溶解させ、ポリマー溶液に添加した。
調製例1のアミノアルキルチオール修飾ポリ酸2.4gおよび酒石酸0.39gを、3.21mLの脱塩水に溶解した(液体1)。
7.9wt%のカンファーキノンおよび5.25wt%のN,N−ジメチルエチレンジアミンを含む、調製例6のアリルアミン修飾ポリ酸の30wt%水溶液(液体2)を調製した。
液体1および液体2を、6:4の比率で、手作業で混合した。
次のステップで、この混合物を、粉末状のストロンチウム−ナトリウム−リン−アルミニウム−フルオロシリケート・ガラスと2:1の比率で、手作業で混合した。
二軸曲げ強度を、直径20mm、厚さ1mmのディスク形状の試験片を使用して測定した。
試験片の調製は、黄色光の条件下で実施した。
試験片を、LicuLite照射オーブン中でそれぞれの側を60秒間照射し、37℃、相対湿度95%で1時間、続いて脱塩水中に37℃で23±0.5時間貯蔵した。
参照例として、非照射試験片を使用した。
すべての試験は、Zwick Z020ユニバーサル試験機で実施した。
