Title:
POROUS POLYMERIC MATERIAL WITH CROSS-LINKABLE WETTING AGENT
Document Type and Number:
WIPO Patent Application WO2008060249
Kind Code:
A9
Abstract:
A porous material is provided which comprises a transparent polymer matrix defining interconnected pores and a wetting agent. At least a portion of the wetting agent is cross-linked with the polymer matrix. A process for forming a porous polymeric material is also provided. A bicontinuous microemulsion comprising water, a wetting agent, a monomer, and a surfactant copolymerizable with the monomer is polymerized, to form a polymer defining interconnected pores. The wetting agent comprises a cross-linkable wetting agent such that after polymerization, at least a portion of the cross-linkable wetting agent is cross-linked with the polymer. The wetting agent may comprise acrylated hyaluronic acid (AHA) such as methacrylated hyaluronic acid (MeHA). The wetting agent may also comprise a hyaluronic acid (HA). The wetting agent may include an unbonded portion that this releasable from the material. A contact lens may be made from the porous material.
