| titleOfInvention | High refractive index ophthalmic device materials |
| abstract | High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymer comprises a) at least two monomers of formula (I) and b) at least one monomer of formula (II) up to about 5 mole% in total:n n n [Formula I]n n n n n n n n [Formula II]n n n n n n n n In the above formula,n n n X is H or CH 3 ;n n n m is 0-10,n n n Y is absent, O, S or NR where R is H, CH 3 , C n H 2n + 1 (n = 1-10), iso-OC 3 H 7 , C 6 H 5 , or CH 2 C 6 H 5 );n n n Ar is unsubstituted or substituted with CH 3 , C 2 H 5 , nC 3 H 7 , iso-C 3 H 7 , OCH 3 , C 6 H 11 , Cl, Br, C 6 H 5 , or CH 2 C 6 H 5 An aromatic ring which may be substituted;n n n W is -CH 3 or (CH 2 = C (-X) -C (= 0)-);n n n n is a weight average molecular weight of about 600-1000 when W is -CH 3 and is about 400-1000 when W is (CH 2 = C (-X) -C (= O)-). |
