Title:

POLYMER AND OPHTHALMIC LENSES MADE BY USING THE SAME

Document Type and Number:

WIPO Patent Application WO/2003/042265

Kind Code:

A1

Abstract:

The invention aims at providing a transparent polymer exhibiting a proper modulus of elasticity, a proper breaking extension and good form recovery properties, and ophthalmic lenses made by using the same. This aim is attained by a polymer comprising as monomer components a siloxanyl monomer (A) having a hydroxyl group, a polydimethylsiloxane (B) having a poly− merizable substituent at one end, and a hydrophilic monomer (C) with proviso that the total content of the monomers (A) and (B) and the content of the monomer (C) are 30 to 95 parts by weight and 5 to 70 parts by weight respectively per 100 parts by weight of the total of the monomers (A), (B), and (C).
