Use is claimed in ophthalmological devices of a polymer composition obtained by polymerization of (A) a main monomer which is a substituted (meth)acrylic ester or a substituted acrylamide of specified formula; (B) a crosslinking monomer; and optionally (C) a comonomer to adjust properties such as refractive index, surface properties, glass transition temperature, strength properties, UV absorption and/or color.

X : O or NR c>; Y : O, S or NR c>; R : 1-6C optionally cyclic hydrocarbon group; R a>H or methyl; R b>H, 1-5C alkyl or Y-Ar 3>; R c>H, 1-6C optionally cyclic hydrocarbon group or aryl; and Ar 1> - Ar 3>aryl bonded to Y by a bridge or via -(CH 2) 0-3-, the aryl optionally having 1-4C substituents comprising 1-5C alkyl or alkoxy or mono- or di-R c>-substituted amino. An independent claim is also included for preparation of the polymer composition. [Image] [Image]. |
