【発明の属する技術分野】
本発明は新規なポリマーから成るプラスチック成形品に関し、透明性、水濡れ性、酸素透過性に優れると共に良好な力学的特性を併せ持つプラスチック成形品として、例えばコンタクトレンズ、眼内レンズなどの眼用レンズに好適に用いられるものである。
【0002】
【従来の技術】
近年高い酸素透過性を有するプラスチック成形品としてトリス(トリメチルシロキシ)シリルプロピルメタクリレートなどのシリル置換メタクリレートや変性ポリシロキサンを一成分とするポリマーが開発され利用されている(特開昭60−142324号、特開昭54−24047号)。
【0003】
しかしながらこれらのモノマー(マクロマー)からなるポリマーは、酸素透過性を向上させる目的で導入されているシリコーンが持つ性質、即ち疎水性と分子間相互作用が小さいという性質のために表面が疎水性となりやすく水をはじいたり汚れが付きやすい、対衝撃性に劣る等の物性上の欠点が存在していた。
【0004】
また、親水性を向上させるために、2−ヒドロキシエチルメタクリレートのような親水性モノマーと前記モノマー(マクロマー)とを共重合させた場合には、極性基である水酸基と非極性基であるシリコン部分との静電的な反発のために相分離が起こり透明なポリマーが得られないという欠点を有していた。
