Title:
AMPHIPHILIC SILOXANE-CONTAINING VINYLIC MONOMERS AND USES THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/093751
Kind Code:
A3
Abstract:
The invention provides an amphiphilic siloxane-containing vinylic monomer of formula (I), polymers made therefrom, an actinically- crosslinkable silicone-containing prepolymer, a silicone hydrogel polymeric material, or a silicone hydrogel contact lens, which comprises monomeric units derived from an amphiphilic siloxane- containing vinylic monomer of the invention. In addition, the invention provides a method for making silicone hydrogel contact lenses using a water-based lens-forming formulation comprising an amphiphilic siloxane-containing vinylic monomer of the invention and/or an actinically-crosslinkable silicone-containing prepolymer of the invention. Formula (I): Q-Xl-hl_-X2-BSi, in which: Q contains a terminal vinylic group, BSi is a siloxane containing hydrophobic group, while the variable hl_ represents a hydrophilic group containing oligomers of -[N(C(=0)R)-CH2-CH2]-, polypeptide segments or polymeric segment from hydrophilic vinylic monomers. The variables are more closely defined in the claims.
