<p>Process for manufacturing an amphoteric polymeric composition wherein a mixture of monomers comprising (i) a monomer selected from the group consisting of acrylamide, methacrylamide, and lower alkyl esters of acrylic and methacrylic acid, and mixtures thereof, and (ii) a monomer selected from the group consisting of a strong mineral acid salt of triallylamine, 1,4-bis (N,N-diallyl-aminomethyl)benzene, 2,4,6-N,N-diallylaminomethyl)toluene, 1,6-bis (N,N-diallylamino)hexane, methyldiallylamine and ethyldiallylamine, and mixtures thereof, is polymerized in the presence of a free radical initiator, wherein the mixture of monomers is dissolved in a polar non-aqueous solvent system, and the resulting polymeric composition is subsequently hydrolyzed.</p> |
