Balanced charge polymer and hydrophilic contact lens manufactured therefrom |
| 摘要 |
<p>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.</p> |
