Patent ID: 11180614

Abstract:
A compound represented by the formula (1) is described, which has a linear polysiloxane structure at the end, a polymerizable group at the other end, and a polyether group or a hydrophilic group as a side chain bounded to a linking group which is represented by -(L1)a-CH-L2- in the formula (1) and exists between the polysiloxane structure and the terminal polymerizable group. The compound has excellent compatibility with a hydrophilic monomer, and the surface wettability of hydrogel obtained from the compound as a monomer is improved. Methods are also described for preparing the polysiloxane monomer compound, a polymer having a repeating unit derived from the polymerization at the (meth)acryl group of the polysiloxane monomer compound, and an ophthalmic device containing the polymer.
