Ophthalmic and otorhinolaryngological device materials

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, CH3, or CH2CH3;
• B=O(CH2)n, NH(CH2)n, or NCH3(CH2)n;
• X=O(CH2)n, NH(CH2)n, NCH3(CH2)n, or nothing;
• n=0-6;
• Y=phenyl, (CH2)mH;
• (CH2)mC6H5, OH, CH2CH(OH)CH2OH, (OCH2CH2)mOCH3, or (OCH2CH2)mOCH2C3;
• m=0-12;
• Z=(CH2)a, (CH2CH2O)b, O, or nothing;
• D=(CH2)a, O(CH2CH2O)b, O, or nothing;
• a=1-12;
• b=1-24;
• A=CH3—, CH3CH2—, CH3CH2CH2—, CH3CH2CH2CH2—, or CH3CH2CH(CH3)—;
• 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.
