Patent ID: 8449610

Claim:
A polymeric ophthalmic or otorhinolaryngological device material comprising a) 50-93% of a polymerizable monomer of the structure: wherein: A is H or CH 3 ; B is (CH 2 ) m or [O(CH 2 ) 2 ] z ; m is 2-6; z is 1-10; Y is nothing, O, S, or NR′, provided that if Y is O, S, or NR′, then B is (CH 2 ) m ; R′ is H, CH 3 , C n′ H 2n′+1 , iso-OC 3 H 7 , C 6 H 5 , or CH 2 C 6 H 5 ; n′=1-10; w is 0-6, provided that m+w≦8; and D is H, Cl, Br, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 6 H 5 , or CH 2 C 6 H 5 ; b) 1-5% of a high molecular weight, linear polyethylene glycol component of the structure: wherein: X, X′ independently=nothing, O, or NH; R, R′ independently=nothing or (CH 2 ) p ; p=1-3; Q, Q′ independently=nothing or C(═O)NHCH 2 CH 2 O; A′=H or CH 3 ; G=H, C 1 -C 4 alkyl, (CH 2 ) m NH 2 , (CH 2 ) m CO 2 H, or R′—X′-Q′—C(═O)C(═CH 2 )A′; and n=45-225 when G=H, C 1 -C 4 alkyl, (CH 2 ) m NH 2 , or (CH 2 ) m CO 2 H; otherwise, n=51-225; and c) a polymerizable cross-linking agent.
