Biocompatible polyurea-urethane hydrated polymers |
摘要 |
<p>A class of hydrophilic prepolymers and hydrated polymer gels is disclosed which are characterized by their transparency, biocompatibility and resistance to nonspecific protein adsorption. At least 75%, preferably at least 90%, of the prepolymers are isocyanate-capped oxyethylene-based diols or polyols having molecular weight of about 7000-30,000. Essentially all of the hydroxyl groups of the diols or polyols are capped with polyisocyanate prior to formation of the hydrated polymer.</p> |
