    • PURPOSE: To obtain a microbicidal composition that comprises a quaternary ammonium polymer prepared by reaction between dimethylamine, a polyfunctional amine and epichlorohydrin, is effective in an aqueous system, non-foamable and non-irritant to human, animals and poultry. CONSTITUTION: This composition is a quaternary ammonium polymer that is prepared by reaction of dimethylamine, a polyfunctional amine (for example, ammonia, primary amine, 2-6C alkylenediamine, polypropylenepolyamine) and epichlorohydrin, and contains the recurring units of formulas I, II, III as the cationic parts, and Br , Cl as the anionic parts. A is the residue after reaction of the polyfunctional amine at least with difunctional epoxy group and the amount of the polyfunctional amine is 1-15mol% based on the total moles of the amines and the epichlorohydrin is in the range from the equimolar amount to the whole functional equivalent of the amine. The application concentration of the polymer is in the range from 0.5-500ppm and the polymer is added every 12 hours so that the final concentration becomes 0.5-10ppm in the recirculation water system in paper industry.
