Abstract:
A polymeric ophthalmic or otorhinolaryngological device material having an elongation of at least 150%, consisting essentially of a single device-forming monomer, a cross-linking monomer, optionally a reactive UV absorber, and optionally a reactive blue-light absorber wherein the cross-linking monomer is CH2&boxH;C(CH3)C(&boxH;O)Oâ€”(CH2CH2O)nâ€”C(&boxH;O)C(CH3)&boxH;CH2 having a number-average molecular weight of about 1000, and wherein the single device-forming monomer is present in an amount of at least about 80% by weight and is an aryl acrylic hydrophobic monomer of the formula wherein; A is CH3, CH2CH3, or CH2OH;B is (CH2)m or (O(CH2)2)n; m is 2-6; n is 1-10; Y is nothing, O, S, or NR, provided that if Y is O, S, or NR, then B is (CH2)m; R is H, CH3, CnH2n+1 (n=1-10), iso-OC3H7, C6H5, or CH2C6H5; w is 0-6, provided that m+w&lE;8; and D is H, C1-C4 alkyl, C1-C4 alkoxy, C6H5, or CH2C6H5.
