Antimicrobial quaternary ammonium group-containing polymers, compositions thereof, and monomers used to produce said polymers

摘要

Antimicrobial quaternary ammonium group-containing organosilicon polymers, aqueous disinfectant solutions containing such polymers, and lenses produced from such polymers are provided herein. The polymers are produced by homopolymerizing or copolymerizing, with a suitable comonomer, a quaternary ammonium group-containing organosilicon monomer of formula I as defined herein. A preferred monomer of formula I is the monomer of formula II: CHEM 3-methacryloxypropyltetramethyldisiloxanylpropyldimethyloctadecylammonium chloride (MADAC).
