Abstract
Abstract Water-soluble polymeric mixtures prepared by mixing 1 to 10 parts by weight of a quaternary ammonium polymer with 0.5 to 7 parts by weight of a high molecular weight nonionic and/or cationic vinyl-addition polymer, and 0.1 to 5 parts by weight of a nonionic and/or cationic surfactant have utility in many diverse applications.
