Patent ID: 8263721

Claim:
A polymeric ophthalmic or otorhinolaryngological device material comprising; a) a monofunctional acrylate or methacrylate monomer [1]; b) a difunctional acrylate or methacrylate cross-linking monomer [2]; and c) an acrylate or methacrylate terminated polystyrene macromer [3] or a diacrylate or dimethacrylate terminated polystyrene macromer [4]; wherein R, R′ independently=H, CH 3 , or CH 2 CH 3 ; B=O(CH 2 ) n , NH(CH 2 ) n , or NCH 3 (CH 2 ) n ; X=O(CH 2 ) n , NH(CH 2 ) n , NCH 3 (CH 2 ) n , or nothing; n=0-6; Y=phenyl, (CH 2 ) m H; (CH 2 ) m C 6 H 5 , OH, CH 2 CH(OH)CH 2 OH, (OCH 2 CH 2 ) m OCH 3 , or (OCH 2 CH 2 ) m OCH 2 C 3 ; m=0-12; Z=(CH 2 ) a , (CH 2 CH 2 O) b , O, or nothing; D=(CH 2 ) a , O(CH 2 CH 2 O) b , O, or nothing; a=1-12; b=1-24; A=CH 3 —, CH 3 CH 2 —, CH 3 CH 2 CH 2 —, CH 3 CH 2 CH 2 CH 2 —, or CH 3 CH 2 CH(CH 3 )—; the total amount of monomer of formula (1) is at least 50% (w/w); the total amount of macromers (3) and/or (4) is 5-40% (w/w); and styrenic repeat units shown in macromers (3) and/or (4) are sufficiently repeated such that the material exhibits a Young's Modulus less than 6.0 and an elongation of at least 150%; and an ingredient selected from the group consisting of a polymerizable UV absorber and a polymerizable colorant.
