HIGH IONIC STRENGTH PROCESS FOR CONTACT LENS MODIFICATION |
摘要 |
A process for modifying the surface of a silicon-containing polymer is presented, the process comprising the steps of: forming a reaction mixture comprising the silicon polymer, a polymerization monomer, a free radical initiator system, a salt, and a solvent system, the polymerization monomer comprising a zwitterionic monomer; and polymerizing the monomer in the reaction mixture to form a surface modification polymer on the surface of the silicon-containing polymer. Such a process is useful in controlling the hydrophilicity of a surface, and can be applied to prepare medical devices such as contact lens having a wettable, biocompatible surface. |
