Abstract:
The invention is related to azetidinium-containing copolymers and vinylic monomers and their uses in formation of non-silicone hydrogel coatings on silicone hydrogel contact lenses.

Claim (Index 14):
The method of  claim 13 , wherein the thermally-crosslinkable hydrophilic polymeric material is:\n (i) a second azetidinium-containing copolymer which comprises second azetidinium-containing monomeric units, reactive monomeric units which are second carboxyl-containing monomeric units and/or second amino-containing monomeric units, and non-reactive hydrophilic monomeric units; (ii) a reaction product of the second azetidinium-containing copolymer with at least one hydrophilicity-enhancing agent having at least one reactive functional group selected from the group consisting of amino group, carboxyl group, thiol group, and combinations thereof; (iii) a reaction product of polyaminoamide-epichlorohydrin with at least one hydrophilicity-enhancing agent having at least one reactive functional group selected from the group consisting of amino group, carboxyl group, thiol group, and combinations thereof; (iv) a water-soluble hydrophilic polymer having at least one reactive functional group selected from the group consisting of amino group, carboxyl group, thiol group, and combinations thereof; or (v) combinations thereof, wherein the second azetidinium-containing monomeric units are derived from at least one second azetidinium-containing vinylic monomer of formula (1) or (2) as defined in  claim 13 , wherein the second carboxyl-containing monomeric units are derived from at least one second carboxyl-containing vinylic monomer, wherein the second amino-containing monomeric units are derived from at least one second amino-containing vinylic monomer, wherein the non-reactive hydrophilic monomeric units are derived from at least one hydrophilic vinylic monomer selected from the group consisting of (meth)acrylamide, N,N-dimethyl (meth)acrylamide, N-vinylpyrrolidone, N,N,-dimethylaminoethyl (meth)acrylate, N,N-dimethylaminopropyl (meth)acrylamide, glycerol methacrylate, 3-acryloylamino-1-propanol, N-hydroxyethyl acrylamide, N-[tris(hydroxymethyl)methyl]-acrylamide, N-methyl-3-methylene-2-pyrrolidone, 1-ethyl-3-methylene-2-pyrrolidone, 1-methyl-5-methylene-2-pyrrolidone, 1-ethyl-5-methylene-2-pyrrolidone, 5-methyl-\u03b2-methylene-2-pyrrolidone, 5-ethyl-3-methylene-2-pyrrolidone, 2-hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, C 1 -C 4 -alkoxy polyethylene glycol (meth)acrylate having a weight average molecular weight of up to 1500 Daltons, N-vinyl formamide, N-vinyl acetamide, N-vinyl isopropylamide, N-vinyl-N-methyl acetamide, allyl alcohol, vinyl alcohol which is the hydrolyzed form of vinyl acetate in the azetidinium-containing copolymer, a phosphorylcholine-containing vinylic monomer, erythritol (meth)acrylate, arabitol (meth)acrylate, mannitol (meth)acrylate, ducitol (meth)acrylate, fucitol (meth)acrylate, iditol (meth)acrylate, innositol (meth)acrylate, xylitol (meth)acrylate, sorbitol (meth)acrylate, glucose (meth)acrylate, fructose (meth)acrylate, galactose (meth)acrylate, and combinations thereof.
