摘要：

The invention provides an amphiphilic siloxane-containing (meth)acrylamide which comprises one sole (meth)acrylamido group, one sole tris(trimethylsiloxy)silyl group, and one polyethylene glycol segment which is either dangling polymer chain or a hydrophilic linker between the (meth)acrylamido group and the tris(trimethylsiloxy)silyl group. The present invention is also related to a polymer, 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 (meth)acrylamido group, one tris(trimethylsiloxy)silyl group 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 (meth)acrylamido group, one tris(trimethylsiloxy)silyl group of the invention and/or an actinically-crosslinkable silicone-containing prepolymer of the invention.
