  • Polymer material, ophthalmic lens and contact lens
    Patent number: 9034942
    Abstract: Provided is a polymer material having superior water wettability and lubricity, and enabling persistence of the same by allowing the surfactant to be retained by the polymer material so as not to be gradually released. The present invention is directed to a polymer material including: [I] a polymer having a constitutional unit derived from (A) a polymerizable compound having an acryloyloxy group and not having a silicon atom; and [II] a surfactant. The content of the surfactant [II] is preferably 0.05% by mass or greater and 1% by mass or less. The surfactant [II] is preferably a nonionic surfactant having a polyoxyethylene group.
    Type: Grant
