摘要:
Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing photoinitiator groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
摘要:
A curable composition is described comprising a Michael donor component, a polyacryl component, and 1) an ethylenically unsaturated monomer having a reactive azlactone functional group, or 2) an ethylenically unsaturated monomer having a reactive ring-opened azlactone functional group. A telechelic polymer that is the reaction product of these components is also described.
