Abstract: The invention relates to a polymer derived from: reaction of glycidyl (meth)acrylate, allyl glycidyl ether or [(vinyloxy)methyl]oxirane with ammonia or primary amine to obtain a mixture of monomer compounds; reaction of the mixture of monomer compounds with at least one of acrylic acid, vinyl alcohol, vinyl acetate, acrylamide, methylacrylic acid, and methylacrylamide to obtain an intermediate polymer; and reaction of the intermediate polymer with a dithiocarbamic acid salt. Methods for using the polymer are also described herein.
