Abstract:
1. A polymeric ophthalmic or otorhinolaryngological device material comprising a) a principal device-forming monomer which is an aryl acrylic hydrophobic monomer of the formula b) a dimethylacryloxypropyl-terminated polydimethylsiloxane macromer in an amount effective to reduce the tack of the polymeric ophthalmic or otorhinolaryngological device material, wherein the dimethylacryloxypropyl-terminated polydimethylsiloxane macromer has the formula c) a cross-linking monomer, wherein the principal device-forming monomer is present in an amount of at least about 75% (w/w), wherein the dimethylacryloxypropyl-terminated polydimethylsiloxane macromer is present in an amount from 0.5-3.9% (w/w), wherein the cross-linking monomer is present in an amount of about 0.01-17% (w/w).
