摘要：
PROBLEM TO BE SOLVEDTo provide an ophthalmic lens, which can be more safely worn, that is, to provide a material, which is transparent and has high oxygen permeability and a high hydrophilic property, and to provide a novel monomer to be a raw material thereof.SOLUTIONA hydrophilic polysiloxane macromonomer contains polyoxyethylene as a hydrophilic side chains in a polysiloxane main chain, wherein transparency, oxygen permeability, and hydrophilic properties of the material are controlled by regulating the length of the polysiloxane main chain, the length of the hydrophilic polyoxyethylene side chains, and the number of the side chains.
