Abstract:
A water-soluble polyvinylpyrridinium derivative copolymer comprising a quaternary nitrogen and an anionic moiety selected from a sulfonate or a carboxylate functionality, said polyvinylpyrridinium derivative copolymer having the structure ##STR4##wherein a is a repeating unit of 1 to 100; b is a repeating unit of 0 to 99; c is a repeating unit of 0 to 99: d is a repeating unit of from 1 to 99: R is selected from the group consisting of (CR.sub.1 R.sub.2).sub.m1, benzene, and substituted benzene; Y is selected from the group consisting of (CR.sub.3 R.sub.4).sub.m2, benzene, and substituted benzene; substituted benzene is independently a benzene substituted with a group selected from the group consisting of amino moeity, nitro moiety, halogen moiety, and combinations thereof; Z is derived from an ethylenically unsaturated monomer, m.sub.1 and m.sub.2 are independently 0 to 10; M.sup.+ is independently a cation wherein M is selected from the group consisting of hydrogen, ammonia, alkali metals, alkaline earth metals, zinc, copper, organic amines, amino acids, and amino saccharides; R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are independently selected from the group consisting of hydrogen, hydroxyl, alkyl having C.sub.1 to C.sub.6, aryl having C.sub.6 to C.sub.18, and alkaryl having C.sub.7 to C.sub.18 ; R.sub.5, R.sub.6, and R.sub.7 are hydrogen; and X.sup.- is independently a halide,with the proviso that if Y is benzene or substituted benzene then a is 0 to 99 and b is 1 to 100;and wherein the ethylenically unsaturated monomer is selected from the group consisting of dimethylaminoethyl acrylate, dimethylaminoethyl methacrylate, diethylaminoethyl acrylate, diethylaminoethyl methacrylate, dimethylaminopropyl acrylate, dimethylaminopropyl methacrylate, diethylaminopropyl acrylate, diethylaminopropyl methacrylate, dimethylaminobutyl acrylate, dimethylaminobutyl methacrylate, dimethylaminoneopentyl acrylate, dimethylaminoneopentyl methacrylate, dimethylaminoethylacrylamide, dimethylaminoethylmethacrylamide, diethylaminoethylacrylamide, diethylaminoethylmethacrylamide, dipropylaminoethylacrylamide, dipropylaminoethylmethacrylamide dimethylaminopropylacrylamide, dimethylaminopropylmethacrylamide, dimethylaminopropylacrylamide, diethylaminopropylmethacrylamide, dimethylaminoneopentylacrylamide, dimethylaminoneopentylmethacrylamide, dialkylaminobutylacrylamide, vinyl pyrrolidone, vinyl imidazolidone, dimethylaminoethylmethacrylate, and dimethylaminoethylacrylate. and combinations thereof.
