    • 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.
    • 本发明提供了式(I)的两亲性含硅氧烷的乙烯基单体,由其制备的聚合物,可光化交联的含硅氧烷的预聚物,硅氧烷水凝胶聚合物材料或硅氧水凝胶隐形眼镜,其包含衍生自两亲性的单体单元 本发明的含硅氧烷的乙烯基单体。 此外,本发明提供使用包含本发明的两亲性含硅氧烷的乙烯基单体和/或本发明的可光化交联的含硅氧烷预聚物的水性透镜形成剂制备硅酮水凝胶隐形眼镜的方法。 式(I):Q-X1-H1-X2-BSi,其中:Q包含末端乙烯基,BSi是含有疏水基团的硅氧烷,而变量h1表示含有 - [N(C( = 0)R)-CH 2 -CH 2] - ,亲水乙烯基单体的多肽片段或聚合物片段。 这些变量在权利要求中更加紧密地定义。
