Title:
【発明の名称】平衡電荷ポリマー及びそれからつくられた親水性コンタクトレンズ
Document Type and Number:
Japanese Patent JPH06508858
Kind Code:
A
Abstract:
A water swellable crosslinked polymer of essentially balanced charge is obtained by polymerizing a polymer-forming composition comprising a cationic-anionic pair of ethylenically unsaturated monomers and a non-ionic ethylenically unsaturated hydrophillic and/or hydrophobic monomer. Contact lenses formed from the polymer exhibit little if any tendency to attract soils, eg proteinaceous debris, to their surfaces.
