表1に示す重合成分、及び重合開始剤として2,2’−アゾビス(2,4−ジメチルバレロニトリル)を、基材全体の100質量部に対して0.5質量部混合し、これを所望のレンズ形状の鋳型内に注入した。この鋳型を80℃のオーブン中に入れて40分間にわたって加熱重合成形を行った。得られた重合体を鋳型から脱型し、溶出処理を行った後、60℃のオーブン内で乾燥させ、レンズ形状の眼内レンズ用材料(実験例1〜14)を得た。また、同様に、表2〜4に示す重合成分を用い、所望のプレート形状の鋳型内に注入し上述と同様の工程を行い、プレート形状の眼内レンズ用材料(実験例15〜60)を得た。必要な測定項目にあわせ、同じ番号(組成)のプレート試料として2種類の厚さの試料を適宜作製した。以下記載の厚さ0.5mmまたは0.8mmのプレートとは、厚さ0.5mmまたは0.8mmのスペーサーを用いた鋳型から作製されたプレートである。試験の目的に合わせ、乾燥したプレートを直径6mmまたは8mmにくり抜いて測定用のプレートとした。
(加水分解処理)
予め試料を60℃にて乾燥し、処理前質量W0を測定した。100mL耐圧瓶に蒸留水50mLを入れ、試料を浸漬した。100℃の乾燥機に耐圧瓶を入れ保存した。試料として直径6mm厚さ0.5mmのプレートを10枚使用した。瓶の風袋質量W01、蒸留水添加後の瓶質量W02、試料浸漬後の瓶質量W03を記録した。
以下の手順によって、加水分解処理30日後の抽出液について、フェノキシエチルアルコール(POEtOH,POEAの加水分解物)の濃度と溶出率を求めた。抽出液採取前の瓶質量W11を記録後、瓶から抽出液を採取し、抽出液採取後の瓶質量W12を記録した。採取した抽出液、標準液、及びそれらのブランク(蒸留水)をHPLCを用いて分析した。分析後、採取した水溶液及び標準溶液のクロマトグラムから蒸留水のクロマトグラムを差し引き、ベースライン補正を行った。補正したクロマトグラムからPOEtOHのピーク面積を算出した。標準液のPOEtOH濃度とピーク面積から検量線を作成した。抽出液のPOEtOHのピーク面積と得られた検量線をもとに、抽出液中のPOEtOHの濃度を算出した。得られたPOEtOHの濃度を用いて、試料1gあたりのPOEtOHの溶出率を次式(1)より算出した。抽出液容量については式(2)より算出した。抽出液容量の算出にあたっては、100℃の加熱により変化した質量のうち試料の質量変化は抽出液のそれに比べて無視できる程小さいこと、抽出液の大部分は水のため密度を1g/1mLとして計算して差し支えないとの考えが前提にある。処理30日の抽出液分析後、再び瓶を100℃の乾燥機に入れた。加水分解処理の合計60日後に、抽出液を再び採取した。処理30日の際と同様に、抽出液採取前の瓶質量W21を記録し、抽出液中のPOEtOH濃度をHPLC分析にて定量し、POEtOHの溶出率を式(3)より算出した。抽出液容量については式(4)より算出した。また、同様に加水分解処理の合計90日後のPOEtOHの溶出率も算出した。
POEtOH溶出率(%)=抽出液中のPOEtOH濃度(ppm)×10-6×抽出液容量V1S(mL)/処理前質量W0(g)×100 …数式(1)
抽出液容量V1S(mL≒g)=[W02(g)−W01(g)]−[W03(g)−W11(g)] …数式(2)
POEtOH溶出率(%)=抽出液中のPOEtOH濃度(ppm)×10-6×抽出液容量V2S(mL)/処理前質量W0(g)×100 …数式(3)
抽出液容量V2S(mL≒g)=V1S(mL≒g)−[W11(g)−W12(g)]−[W12(g)−W21(g)] …数式(4)
この測定において、直径6mm、中心厚み0.8mm±0.1mmのレンズ形状の試料あるいは直径6mm、厚さ0.5mmのプレートの試料を使用した。レンズ形状の試料については、試料を35℃の水中に17時間以上浸漬し、次いで25℃の水中に2時間浸漬した後、実体顕微鏡にて外観を観察した。プレートの試料については、試料を35℃の水中に22時間浸漬し、次いで25℃の水中に2時間浸漬した後、実体顕微鏡にて外観を観察した。外観の観察は、1種の試料につき2あるいは3検体行い、グリスニング(輝点)の発生個数を調べた。倍率は約10〜60倍であった。グリスニングを観察しやすいよう上記範囲で倍率を適宜調節し観察した。
25℃における平衡含水状態及び乾燥状態での試料の質量を測定し、吸水率(質量%)を算出した。吸水率は、25℃における平衡含水状態での試料の質量Ww、乾燥状態での試料の質量Wdとにより、次式(5)より算出した。試料として、直径6mm厚さ0.8mmのプレートを5枚使用した。
吸水率(質量%)=(Ww−Wd)/Wd×100 …数式(5)
アッベ屈折計を用いて試料のHg−e線による屈折率を求めた。乾燥状態の試料(25℃)あるいは吸水状態の試料(35℃)で測定した。試料として、直径6mm厚さ0.8mmのプレートを使用した。
以下の手順で直径6mm厚さ0.5mmのプレートを圧縮し座屈(曲げ座屈)させ、6mmから3mmへ試料が折りたたまれた際の荷重値を圧縮荷重値として測定した。測定前の試料を23℃50%RHの環境下に放置し状態調節をした。図1は、圧縮荷重の測定に使用した圧子10及び治具11を側面から見た図である。圧子10及び治具11はポリオキシメチレン(ジュラコン)であり、円柱状である。圧子10及び治具11をクリープメータ(山電製RE2−33005S)に取り付けた。治具11上面の試料設置部分に両面テープ(3M Scotch Brand Tape core series 2-0300)をつけておき、試料12を設置した。治具11を取り付けた試料台(土台)部分を上下させ、圧子10と試料12とを接触させた。圧縮速度0.5mm/secで接触位置から3.2mm試料台部分を上昇させ、試料を座屈させた。3mm上昇した際の荷重を圧縮荷重値とした。
この測定において、直径8mm、厚さ0.8mmのプレートを使用した。クリープメータの試料台(土台)部分に粘着性測定用の治具を取り付けた。治具の一部を取り外し、取り外した治具の一部に試料をはめ、治具と試料が一体になったものをクリープメータに取り付けた。試料台を動かし、試料と金属製プローブ(曲率半径2.5mm)が接触して0.05Nの力がかかった状態とし、その位置で台を停止させた。停止してから約5秒後に引き離し速度1mm/secで試料とプローブを引き離し、その際プローブにかかる荷重をクリープメータ(山電製RE2−33005S)で測定した。測定された最大荷重から、プローブが試料から離れた後の荷重(脱離後の荷重)を差し引いた値を、粘着性の値として算出した。粘着性の値が、0N以上0.16N未満を「A」、0.16N以上0.30N未満を「B」、0.30N以上を「C」として評価した。
全長(L0)約20mm、平行部長さ(L)6mm、平行部幅(W)1.5mm、厚さ0.8mmのダンベル形状の試験片(図2参照)を用いて測定した。25℃の恒温水に試料を浸漬して1分間静置した後、100mm/分の速度で破断するまで引っ張った。ソフトウェアを用いて、最大荷重時の歪み(=伸び率(%))を求めた。
レンズ形状の実験例1〜14の結果を表5に、プレート形状の実験例15〜60の結果を表6〜9に示す。表6〜9の結果から、メタクリレート構造の増加により加水分解の抑制が可能であること、及びそのようなメタクリレート成分としてアルコキシメタクリレートが好適であることがわかった。表5の実験例1〜6は、特許文献1に記載の組成から基材であるアクリレート(POEA、EA)の含量を減らし、POEMA、EHMA、LMAを添加した組成である。LMAを添加した実験例1〜3は粘着性が高く、脆く破れやすく、グリスニングの発生しやすい材料であった。EHMAを添加した実験例4はグリスニングの発生しやすい材料であった。POEMAを添加した実験例5及び6はグリスニングが発生しやすく、硬い材料であった。それらに比べアルコキシメタクリレートであるETMAを添加した実験例7〜14は、粘着性が低く、脆くない材料であった。
