(1)複数種のモノマーを含有する重合原液を重合することにより得られるシリコーンハイドロゲルであって、該重合原液が、モノマー混合物中のモノマー成分およびポリマー成分の合計量を基準として、約30〜約98重量%の少なくとも1種のシリコーンモノマーと、下記式で表される約1〜約50重量%の少なくとも1種の非シリコーン系(メタ)アクリルアミドモノマーとを含有する、シリコーンハイドロゲル。
ただし、以下のシリコーンハイドロゲルを除く。
複数種のモノマーを含む重合原液を重合することにより得られるシリコーンハイドロゲルであって、
該重合原液が、少なくとも1種類の、分子内に重合性基とシロキサニル基を有するシリコーンモノマーを、モノマー成分およびポリマー成分の合計量に対して30〜98重量%含み、かつ少なくとも1種類の、分子内に2つ以上の水酸基を有する非シリコーン系(メタ)アクリルアミドモノマーを、モノマー成分およびポリマー成分の合計量に対して1〜50重量%含み、
前記分子内に2つ以上の水酸基を有する非シリコーン系(メタ)アクリルアミドモノマーが下記一般式(c1)〜(c3)のいずれかで表され、
前記シリコーンモノマーのうち少なくとも一部がシリコーン(メタ)アクリルアミドモノマーであって、前記重合原液中のモノマー成分の合計量に対する(メタ)アクリルアミドモノマーの含有量の合計が90重量%以上である、シリコーンハイドロゲル。

(A)モノマー成分およびポリマー成分の合計量に対して30〜98重量%の、少なくとも1種のシリコーンモノマー、および
(B)モノマー成分およびポリマー成分の合計量に対して1〜50重量%の、分子内に2つ以上の水酸基を有する非シリコーン系(メタ)アクリルアミドモノマーを含むモノマー混合物を重合することにより得られる。

実施例1〜17の測定方法
全光線透過率は、SMカラーコンピュータ(型式SM−7−CH、スガ試験機株式会社製)を用いて測定した。レンズサンプルの水分を軽く拭き取り、次にサンプルを光路内にセットして測定を行った。ABCデジマチックインジケータ(ID−C112、株式会社ミツトヨ製)を用いて厚みを測定し、厚みが0.14〜0.15mmであるサンプルを測定した。
レンズサンプルから、最も狭い部分の幅5mmのアレイ型サンプルを切り出し、ABCデジマチックインジケータ(ID−C112、株式会社ミツトヨ製)を用いて厚みを測定し、次にテンシロン(東洋ボールドウィン社製RTM−100、クロスヘッド速度100mm/分)により、弾性率および伸度を測定した。
シリコーンハイドロゲルの含水状態の重量(W1)、および乾燥状態の重量(W2)を測定し、次式により含水率を算出した。
含水率(%)=(W1−W2)/W1×100
レンズサンプルから、幅5mmの短冊状サンプルを切り出し、レスカ社製動的接触角計WET−6000を用いて動的接触角の測定を行った(浸漬速度7mm/分)。
レンズ中央付近から幅5mm、長さ約1.5cmの短冊状サンプルを切り出し、(株)サン科学製レオメータCR−500DXを用いて測定した。チャック幅5mmにてサンプルを取り付け、速度100mm/分で5mm引っ張った後、このサンプルを同速度で初期長(5mm)まで戻す、というこのサイクルを3回繰り返した。サンプルを初期長まで戻す2回目の途中で応力がゼロになった時点から3回目の引っ張りサイクル開始後に応力がかかり始めた(応力がゼロでなくなった)時点までの時間の長さを求め、応力ゼロ時間とした。応力ゼロ時間は、短いほどシリコーンハイドロゲルの形状回復性が良好であることを示し、値は2秒以下が好ましく、1.5秒以下がより好ましく、1.2秒以下が最も好ましい。
下記式(s1)
表1に示す通りに組成を変更する以外は実施例1と同様の方法で重合を行いレンズサンプルを得た。得られたサンプルの外観、全光線透過率、含水率、弾性率および伸度は表1に示す通りであった。
非シリコーン系アクリルアミドモノマーとして、式(h1)で表されるモノマーの代わりに下記式(h2)
表1に示す通りに組成を変更する以外は実施例7と同様の方法で重合を行いレンズサンプルを得た。得られたサンプルの外観、全光線透過率、含水率、弾性率および伸度は表1に示す通りであった。
非シリコーン系アクリルアミドモノマーとして、式(h1)で表されるモノマーの代わりに下記式(h0)
シリコーンアクリルアミドモノマーとして下記式(s2)
非シリコーン系アクリルアミドモノマーとして式(s2)で表されるモノマーを用い、またシリコーンアクリルアミドモノマーとして式(h0)で表されるHEAAを用い、表2に示す組成で実施例1と同様の方法でレンズサンプルを作製した。得られたサンプルの全光線透過率、含水率、弾性率および伸度は表2に示す通りであった。比較例6〜9の結果を実施例12〜16と比較すると、HEAAはこれらの系に関しては相溶化剤として十分でないことがわかる。メタクリレートのバージョンである2−ヒドロキシエチルメタクリレートはシリコーンハイドロゲル中で相溶化成分として機能しているので、これは驚くべきことである。しかしながら、HEAAを用いた比較例6〜9の配合は望ましい低い弾性率を示している。
表3に示す成分を、希釈剤45重量%に対して成分55重量%の比率で、Ν,Ν’−メチレンビスアクリルアミド(MBA、1.1重量%)、2−(2’−ヒドロキシ−5’−メタクリロイルオキシエチルフェニル)−2H−ベンゾトリアゾール(ノルブロック(Norbloc)、2.2重量%)、光開始剤イルガキュア819(0.25重量%)および溶媒としての第三級アミルアルコール(t−AA)と共にブレンドして混合した。表3では以下の頭字語を用いる。
(s1)は、下記式のシリコーンモノマーである。
F=2γpcosθまたはθ=cos−1(F/2γp)
式中、Fは湿潤力、γはプローブ液の表面張力、pはサンプルのメニスカス部の周長、θは接触角である。前進接触角は、湿潤実験におけるサンプルを包装溶液中に浸漬している部分から得られる。各サンプルについて4サイクル行って結果を平均してレンズの前進接触角を得る。
表3に示す通りに組成を変更する以外は実施例17と同様の方法で重合を行いレンズサンプルを得た。レンズのヘイズ、含水率、動的接触角(DCA)および弾性率についての測定値を表3に列挙する。
表3に示す通りに組成を変更する以外は実施例17と同様の方法でレンズサンプルを作製した。レンズのヘイズ、含水率、動的接触角(DCA)および弾性率についての測定値を表3に列挙する。実施例20〜22と実施例17を比較すると、PVP含有量を減らした場合、得られるレンズは透明であるが湿潤性が低いことがわかる。実施例23〜25と実施例17を比較すると、PVP含有量を増やすかまたは非シリコーン系モノマーを(h2)に変更した場合、得られるレンズは湿潤性であるが透明性が低いことがわかる。
式(h2)の非シリコーン系(メタ)アクリルアミドモノマーを用いる以外は、実施例17と同様の方法でレンズサンプルを作製した。
2−(N−メチルアミノ)エタノール(7.88g、0.105mol)とテトラヒドロフラン(100mL)を300mL三つ口フラスコに入れ、氷浴(−10〜−5℃)に入れたままおよそ20分間かけて滴下漏斗でアクリル酸クロリド(4.1mL、0.05mol)を滴下した。
2−(N−メチルアミノ)エタノールの代わりに1−(N−メチルアミノ)−2,3−ジヒドロキシプロパンを用いる以外は、モノマー合成1と同様の方法でモノマーを合成した。下記式(h4)
非シリコーン系アクリルアミドモノマーとして、式(h1)で表されるモノマーの代わりに式(h3)および(h4)で表されるモノマーを用い、表4に示す通りに組成を変更する以外は、実施例1と同様の方法でレンズサンプルを作製した。得られたサンプルの外観、全光線透過率、含水率、弾性率および伸度は表4に示す通りであった。
