分析方法
GPC測定は、以下の条件にて行った。
機器:東ソー株式会社
カラム:TSKgel SUPER HM H、2カラム(粒径;5μm、6.0mmID×15cm)
移動相:N−メチルピロリドン(10mM LiBr)
カラム温度:40℃
測定時間:40分
注入量:10μL
検出器:RI検出器
流速:0.2mL/分
試料濃度:0.4重量%
標準試料:ポリスチレン(分子量500〜109万)
2000ppmのブロックコポリマーを溶解させた包装溶液を石英セルに入れ、スガ試験機株式会社製カラーコンピュータ(SM7−CH型)にて透過率を測定した。
レンズの湿潤性は、室温でKRUSS DSA−100 TM機器を用い、プローブ溶液として脱イオン水を用いて測定し、液滴法により求めた。試験するレンズ(3〜5/試料)を脱イオン水中ですすいで包装溶液の残渣を除去した。各試験用レンズを、「くぼみ側を下」にしてレンズホルダーの凸面に設置し、シリンジが正確に中央になるように位置を揃え、シリンジが指定の液体に対応していることを確認した。吸取紙(ガラス板上の乾燥ワットマン#1濾紙)を、20秒間下方への圧力を加えずにレンズに静かに置く。DSA 100−Drop Shape Analysisソフトウェアを用いて、3〜4マイクロリットルの脱イオン水の液滴を、確実にレンズから離れて垂れているようにシリンジの先端に形成させた。針を下に動かして液滴をレンズ表面に滑らかに放った。針は、液滴を分注した後直ちに回収した。液滴をレンズ上で5〜10秒間平衡に保ち、測定した液滴像とレンズ表面との接触角を基に接触角を算出した。
調査対象の各レンズタイプについて標準曲線を設定した。タグ付きコレステロール(NBD([7−ニトロベンズ−2−オキサ−1,3−ジアゾール−4−イル]で標識化されたコレステロール、CH−NBD;アヴァンティ社(Avanti)、アラバマ州アラバスター))を、35℃の脂質/メタノール(1mg/mL)の原液中で可溶化した。この原液からアリコートを取り出して、pH7.4、濃度範囲0〜100micg/mLのリン酸緩衝生理食塩水(PBS)中における標準曲線を作成した。
4,4’−アゾビス(4−シアノ吉草酸)1.68g(6mmol)、4−ジメチルアミノピリジン1.83g(15mmol)、Ν,Ν−ジシクロヘキシルカルボジイミド3.0g(15mmol)及びアセトン40mLを、塩化カルシウム管を備えた200mL三つ口フラスコに、窒素ガスを通じながら加えた。一方の末端にヒドロキシル基を有し下記式(a2)で表されるポリジメチルシロキサン(チッソ株式会社製FM−0411、Mw:1000)8.58g(9mmol)をこの溶液に滴加し、室温で6時間撹拌した。
4,4’−アゾビス(4−シアノ吉草酸)1.40g(5mmol)、一方の末端にアミノ基を有し下記式(a3)で表されるポリジメチルシロキサン(チッソ株式会社製、FM0311、Mw:1000)9.1g(9.1mmol)、4−ジメチルアミノピリジン0.67g(5.5mmol)及びアセトン50mLを、塩化カルシウム管を備えた200mL三つ口フラスコに窒素ガスを通じながら加えた。
一方の末端にヒドロキシル基を含むポリジメチルシロキサン(a2)に代えて、同じ構造であるが分子量がより大きいポリジメチルシロキサン(チッソ株式会社製、FM−0421、Mw:5000)を用いた以外は、実施例1と同様の方法を用いてシリコーン部分の分子量が5000のシリコーンマクロ開始剤を得た。得られたシリコーンマクロ開始剤を、実施例1に記載のように精製した。
