The present invention provides a TRIS-containing vinyl monomer containing only one (meth) acryloyloxy group and a tris (trimethylsiloxy) silyl group covalently bonded to the ethylenically unsaturated group via a polyoxyethylene linking chain. To do. The present invention also relates to polymers, actinically crosslinkable silicone-containing prepolymers, silicone hydrogel polymer materials, or silicone hydrogel contact lenses comprising monomer units derived from the TRIS-containing vinyl monomers of the present invention. Furthermore, the present invention provides a method for producing the TRIS-containing vinyl monomer of the present invention. |
