MONOMER COMPOSITION FOR CONTACT LENSES, POLYMER FOR CONTACT LENSES AND METHOD FOR PRODUCING SAME, AND CONTACT LENS AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2020/218220

Kind Code:

A9

Abstract:

The present invention provides a monomer composition for contact lenses that exhibit good surface hydrophilicity, good oxygen permeability, while having excellent modulus and excellent elongation at break, said monomer composition producing a polymer using a polysiloxane monomer.　It is found that the above objective is able to be achieved by a monomer composition which contains a phosphorylcholine group-containing polysiloxane monomer, a monovinyl ether monomer or the like.
